Neutralization of IL-9 Ameliorates Experimental Autoimmune Encephalomyelitis by Decreasing the Effector T Cell Population
Authors: Li Hongmei , Nourbakhsh Bardia , Ciric Bogoljub , Zhang Guang-Xian , Rostami Abdolmohamad
Published: August 2010

Multiple sclerosis is a CD4+ T cell-mediated autoimmune disease affecting the CNS. Multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE), have been thought to be Th1-mediated diseases. However, recent studies provide strong evidence that the major pathogenic T cell subsets in EAE are Th17 cells. IL-9, a hematopoietic growth factor, is considered to be a mediator of Th17 cells, but the precise mechanisms of its action are largely unknown. The present study was designed to investigate the role of IL-9 in autoimmune demyelination. IL-9 blockade with anti–IL-9 mAb inhibited the development of EAE, reduced the serum levels of IL-17, the CNS mRNA expression of IL-17, IL-6, IFN-γ, and TNF-α, and the myelin oligodendrocyte glycoprotein (MOG)-induced IL-17, IFN-γ secretion of lymphocytes. Furthermore, anti–IL-9 mAb in culture suppressed IL-17 production of MOG-reactive T cells and their potency in adoptive transfer EAE. These findings indicate that the protective effect of IL-9 blockade in EAE was likely mediated via inhibition of the development of MOG peptide-specific T cells, which in turn led to reduced infiltration of T cells into the CNS. Thus, anti–IL-9 mAb treatment may provide an effective therapeutic strategy against autoimmune diseases.

Immunodeficiency in chronic granulomatous disease (CGD) is well characterized. Less understood are exaggerated sterile inflammation and autoimmunity associated with CGD. Impaired recognition and clearance of apoptotic cells resulting in their disintegration may contribute to CGD inflammation. We hypothesized that priming of macrophages (Mϕs) with IFN-γ would enhance impaired engulfment of apoptotic cells in CGD. Diverse Mϕ populations from CGD (gp91phox−/−) and wild-type mice, as well as human Mϕs differentiated from monocytes and promyelocytic leukemia PLB-985 cells (with and without mutation of the gp91phox), demonstrated enhanced engulfment of apoptotic cells in response to IFN-γ priming. Priming with IFN-γ was also associated with increased uptake of Ig-opsonized targets, latex beads, and fluid phase markers, and it was accompanied by activation of the Rho GTPase Rac. Enhanced Rac activation and phagocytosis following IFN-γ priming were dependent on NO production via inducible NO synthase and activation of protein kinase G. Notably, endogenous production of TNF-α in response to IFN-γ priming was critically required for inducible NO synthase upregulation, NO production, Rac activation, and enhanced phagocytosis. Treatment of CGD mice with IFN-γ also enhanced uptake of apoptotic cells by Mϕ in vivo via the signaling pathway. Importantly, during acute sterile peritonitis, IFN-γ treatment reduced excess accumulation of apoptotic neutrophils and enhanced phagocytosis by CGD Mϕs. These data support the hypothesis that in addition to correcting immunodeficiency in CGD, IFN-γ priming of Mϕs restores clearance of apoptotic cells and may thereby contribute to resolution of exaggerated CGD inflammation.

Maslov class rigidity for Lagrangian submanifolds via Hofer’s geometry
Authors: Kerman Ely , Şirikçi Nil I.
Published: August 2010

In this work, we establish new rigidity results for the Maslov class of Lagrangian submanifolds in large classes of closed and convex symplectic manifolds. Our main result establishes upper bounds for the minimal Maslov number of displaceable Lagrangian submanifolds which are product manifolds whose factors each admit a metric of negative sectional curvature. Such Lagrangian submanifolds exist in every symplectic manifold of dimension greater than six or equal to four.

The proof utilizes the relations between closed geodesics on the Lagrangian, the periodic orbits of geometric Hamiltonian flows supported near the Lagrangian, and the length minimizing properties of these flows with respect to the negative Hofer length functional.
A Comparison of ERP-Success Measurement Approaches
Authors: A. Kronbichler Stephan , Ostermann Herwig , Staudinger Roland
Published: August 2010

ERP projects are complex purposes which influence main internal and external operations of companies. There are different research approaches which try to develop models for IS / ERP success measurement or IT-success measurement in general. Each model has its own area of application and sometimes a specific measurement approach based, for instance, on different systems or different stakeholders involved. This research paper shows some of the most important models developed in the literature and an overview of the different approaches of the models. An analysis which shows the strengths, weaknesses and the cases in which the specific model could be used is made.

Authors: Widdifield Jessica , Bernatsky Sasha , Paterson J. Michael , Thorne J. Carter , Cividino Alfred , Pope Janet , Gunraj Nadia , Bombardier Claire
Published: August 2010

Objective

To estimate the percentage of seniors with rheumatoid arthritis (RA) receiving disease‐modifying antirheumatic drugs (DMARDs) within the first year of diagnosis.

Methods

We assembled an incident RA cohort from Ontario physician billing data for 1997–2006. We used a standard algorithm to identify 24,942 seniors with RA based on ≥2 billing codes ≥60 days apart but within 5 years. Drug exposures were obtained from pharmacy claims data. We followed subjects for 1 year, assessing if they had been exposed (defined as ≥1 prescription) to 1 or more DMARDs within the first year of RA diagnosis. We assessed secular trends and differences for subjects who had received rheumatology care (defined as ≥1 rheumatology encounter) versus those who had not.

Results

In total, only 39% of the 24,942 seniors with new‐onset RA identified over 1997–2006 were exposed to DMARD therapy within 1 year of diagnosis. This increased from 30% in 1997 to 53% in 2006. Patients whose care involved a rheumatologist were more likely to be exposed to DMARDs than those who had no rheumatology care. In 2006, 67% of subjects receiving rheumatology care were exposed to DMARDs versus 21% of those with no rheumatology care.

Conclusion

Improvements in RA care have occurred, but more efforts are needed. Subjects receiving rheumatology care are much more likely to receive DMARDs as compared to those with no rheumatology care. This emphasizes the key role of rheumatologists.

Authors: Shi Wenying , He Shan , Wei Min , Evans David G. , Duan Xue
Published: August 2010

The preparation of a highly oriented photoluminescent film of fluorescein (FLU) and 1‐heptanesulfonic acid sodium (HES) co‐intercalated in a layered double hydroxide (LDH) matrix by electrophoretic deposition (EPD) is reported, and its application as an optical pH sensor is demonstrated. The FLU‐HES/LDH films with thickness ranging from nanometer to micrometer on indium tin oxide substrates exhibite good c‐orientation of LDH platelets (the ab‐plane of the LDH platelets parallel to the substrate), as confirmed by X‐ray diffraction and scanning electron microscopy. Polarized luminescence of the film is observed with anisotropy value r = 0.29, resulting from the highly oriented FLU in the LDH gallery. Furthermore, the optical pH sensor with film thickness of 300 nm exhibits a broad linear dynamic range for solution pH (5.02–8.54), good repeatability (relative standard deviation (RSD) less than 1.5% in 20 consecutive cycles) and reversibility (RSD less than 1.5% in 20 cycles), high photostability and storage stability (ca. 95.2% of its initial fluorescence intensity remains after one month) as well as fast response time (2 s). Therefore, this work creates new opportunities for the preparation and application of LDH‐based chromophores in the field of optical sensors.

Published: August 2010

An increasing number of applications using ultraviolet radiation have renewed interest in ultraviolet photodetector research. Particularly, solar‐blind photodetectors sensitive to only deep UV (<280 nm), have attracted growing attention because of their wide applicability. Among recent advances in UV detection, nanowire (NW)‐based photodetectors seem promising, however, none of the reported devices possesses the required attributes for practical solar‐blind photodetection, namely, an efficient fabrication process, a high solar light rejection ratio, a low photocurrent noise, and a fast response. Herein, the assembly of β‐Ga2O3 NWs into high‐performance solar‐blind photodetectors by use of an efficient bridging method is reported. The device is made in a single‐step chemical vapor deposition process and has a high 250‐to‐280‐nm rejection ratio (∼2 × 103), low photocurrent fluctuation (<3%), and a fast decay time (<<20 ms). Further, variations in the synthesis parameters of the NWs induce drastic changes in the photoresponse properties, which suggest a possibility for tuning the performance of the photodetectors. The efficient fabrication method and high performance of the bridged β‐Ga2O3 NW photodetectors make them highly suitable for solar‐blind photodetection.
Longitudinal study of breastfeeding structure and women's work in the Brazilian Amazon
Authors: Piperata Barbara A. , Mattern Lindsey M. Gooden
Published: August 2010

It is well established that breast milk is the ideal food for infants and that breastfeeding has short‐ and long‐term health benefits for the mother and child. However, there is variation in breastfeeding patterns between populations. Women's work is thought to influence breastfeeding patterns and timing of supplementation and it is often assumed that women in subsistence‐oriented societies can more easily integrate their productive and reproductive activities. This article reports longitudinal data, collected in three rounds (resguardo [<40 days], peak [2–4 months], and late [14–16 months] lactation), on breastfeeding structure, infant care, and work patterns of 17 rural Amazonian women in an effort to understand how breastfeeding structure and maternal time allocation changed over time, as well as the strategies women used to integrate their productive and reproductive roles. Women breastfed 10.6 ± 3.1, 9.4 ± 3.4, and 9.6 ± 5.5 times per 9‐h period in the three rounds, respectively. Breastfeeding structure, specifically session duration, changed over time (P < 0.05). As lactation progressed, women spent less time breastfeeding and in infant care and more time in subsistence work. In peak lactation, subsistence work was negatively correlated with infant care (r = −0.4, P = 0.01), breastfeeding (r = −0.29, P = 0.05) and session duration (r = −0.39, P < 0.01) and in late lactation was negatively correlated with time spent breastfeeding (r = −0.39, P < 0.01) and in infant care (r = −0.50, P < 0.01) and positively correlated with inter‐session interval (r = 0.40, P < 0.01). Generally, women reduced time in subsistence work when breastfeeding was more intense and returned to normal activity patterns once infants were being supplemented. The costs and benefits associated with women's strategies are discussed. Am J Phys Anthropol, 2011. © 2010 Wiley‐Liss, Inc.
Temperature‐dependent pyrolytic product evolution profile for polypropylene
Authors: Hujuri Ujwala , Ghoshal Aloke K. , Gumma Sasidhar
Published: August 2010

The composition of the pyrolysis products of plastics depends on disintegration of the macromolecule into variety of hydrocarbon fractions. In this work, a detailed gas chromatographic study of pyrolysis products of polypropylene (PP) between 200 and 600°C was carried out. The pyrograms have been analyzed in terms of amount of different products evolved at various pyrolysis temperatures. At low pyrolysis temperatures (200–300°C), the yield of lighter hydrocarbons (C5‐C10) is low; it gradually increases until maximum decomposition temperature (446°C) and decreases thereafter. The following reaction types were considered to explain the decomposition mechanism of PP: (a) main chain cleavage to form chain‐ terminus radicals; (b) intramolecular hydrogen transfer to generate internal radicals; (c) intermolecular hydrogen transfer to form both volatile products and radicals; and (d) β‐scission to form both volatiles and terminally unsaturated polymer chains. © 2010 Wiley Periodicals, Inc.

Authors: Xu Yingjun , Yin Hong , Zheng Haifeng , Yuan Shenfeng , Chen Zhirong
Published: August 2010

Amino polysiloxanes (APSs) with different amino values and amino types were synthesized and applied to cotton fabrics. Softening and smoothening properties of the fabrics treated with APSs were investigated and evaluated by measuring wrinkle recovery angles and friction coefficients, and the morphological features of the APSs adsorbed onto cellulose substrate films were characterized by atomic force microscope (AFM). The results indicate that the amino values and amino types of the APSs have a significant impact on the softening and smoothening properties of the fabrics. APSs with relatively high amino values exhibit superior smoothening property, while APSs with moderate amino values exhibit excellent softening property. Compared to the traditional softener N‐β‐aminoethyl‐γ‐aminopropyl polydimethylsiloxane (APS‐1), the new amino type softeners γ‐piperazinylpropyl polydimethylsiloxane (APS‐2) and N‐γ'‐dimethylaminopropyl‐γ‐aminopropyl polydimethylsiloxane (APS‐3) gave better fabric performance, whereas aminopropyl polydimethylsiloxane (APS‐4) and N‐cyclohexyl‐γ‐aminopropyl polydimethylsiloxane (APS‐5) gave unsatisfactory fabric performance. © 2010 Wiley Periodicals, Inc.

Properties and antimicrobial efficacy of cellulose fiber coated with silver nanoparticles and 3‐mercaptopropyltrimethoxysilane (3‐MPTMS)
Authors: Kim Sam Soo , Park Jeong Eun , Lee Jaewoong
Published: August 2010

Silver nanoparticles were coated onto cotton fabrics with 3‐mercaptopropyltrimethoxysilane (3‐MPTMS). The coating process was accomplished by soaking the cotton fabrics into silver colloid/3‐MPTMS solution at 43°C for 90 min. The coated fabrics were characterized by scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). SEM images showed a layer of silver nanoparticles and 3‐MPTMS on cotton. The XPS data showed that distinguishable binding energy peaks of Ag 3d, Si 2p, Si 2s, S 2p were 368/374, 102, 153, and 162 eV, respectively, which confirms the existence of silver and 3‐MPTMS on cotton fabrics. The treated cotton fabrics showed prominent antimicrobial effectiveness against Staphylococcus aureus (ATCC 6538) and Klebsiella pneumonia (ATCC 4352). Furthermore, the laundry test showed that 66% of silver nanoparticles were retained after five washing cycles. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Effect of maleic anhydride grafted ethylene propylene diene monomer (MAH‐g‐EPDM) on the properties of kaolin reinforced EPDM rubber
Authors: Manjhi Sanjay , Sarkhel Gautam
Published: August 2010

Due to pollution issue and dark color of carbon black, nonblack filler are getting more importance for reinforcing elastomer. EPDM‐kaolin composites with variable maleated EPDM concentration have been prepared by mixing on a two roll mill. Optimum cure time increases with increasing compatibilizer concentration without decreasing torque value indicating that acidic functional groups comes from compatibilizer could retard cure rate and increase optimum cure time rather than change in ultimate cure state. As the concentration of filler increases, the edge to edge and face to edge interaction between filler and EPDM increases and the free volume between EPDM molecules is reduced, leading to less solvent swelling increasing crosslinking density. The results obtained shows that with increasing filler concentration the modulus and elongation at break increases due to the intertubular diffusion of EPDM inside the clay. The morphological study revealed that homogeneity of filler dispersion increases with increase in compatibilizer concentration which support the results obtained from tensile test. © 2010 Wiley Periodicals, Inc.

Catalyst‐Controlled Ring‐Opening Cycloisomerization Reactions of Cyclopropenyl Carboxylates for Highly Regioselective Synthesis of Different 2‐Alkoxyfurans
Authors: Chen Jie , Ma Shengming
Published: August 2010

Differently substituted 2‐alkoxyfurans (2,3,4‐ or 2,3,5‐trisubstituted furans) were highly regioselectively synthesized by means of the ring‐opening cycloisomerization of the same cyclopropenyl carboxylates with good yields in different solvents and excellent regioselectivity by using [Cu(acac)2] (acac=acetylacetonate) or [RuCl2(PPh3)3] as the catalyst, respectively. The structures of these two different types of furans were established by X‐ray diffraction studies. A rationale has been proposed.
A hierarchical Bayesian approach to multiple testing in disease mapping
Authors: Catelan Dolores , Lagazio Corrado , Biggeri Annibale
Published: August 2010

We propose a Bayesian approach to multiple testing in disease mapping. This study was motivated by a real example regarding the mortality rate for lung cancer, males, in the Tuscan region (Italy). The data are relative to the period 1995–1999 for 287 municipalities. We develop a tri‐level hierarchical Bayesian model to estimate for each area the posterior classification probability that is the posterior probability that the municipality belongs to the set of non‐divergent areas. We show also the connections of our model with the false discovery rate approach. Posterior classification probabilities are used to explore areas at divergent risk from the reference while controlling for multiple testing. We consider both the Poisson‐Gamma and the Besag, York and Mollié model to account for extra Poisson variability in our Bayesian formulation. Posterior inference on classification probabilities is highly dependent on the choice of the prior. We perform a sensitivity analysis and suggest how to rely on subject‐specific information to derive informativea prioridistributions. Hierarchical Bayesian models provide a sensible way to model classification probabilities in the context of disease mapping.
Coupling glucose fermentation and homoacetogenesis for elevated acetate production: Experimental and mathematical approaches
Authors: Ni Bing‐Jie , Liu He , Nie Yan‐Qiu , Zeng Raymond J. , Du Guo‐Cheng , Chen Jian , Yu Han‐Qing
Published: August 2010

Homoacetogenesis is an important potential hydrogen sink in acetogenesis, in which hydrogen is used to reduce carbon dioxide to acetate. So far the acetate production from homoacetogenesis, especially its kinetics, has not been given sufficient attention. In this work, enhanced production of acetate from anaerobic conversion of glucose through coupling glucose fermentation and homoacetogenesis is investigated with both experimental and mathematical approaches. Experiments are conducted to explore elevated acetate production in a coupled anaerobic system. Acetate production could be achieved by homoacetogenesis with a relative high acetate yield under mixed fermentation conditions. With the experimental observations, a kinetic model is formulated to describe such a homoacetogenic process. The maximum homoacetogenic rate (km,homo) is estimated to be 28.5 ± 1.7 kg COD kg−1 COD day−1 with an uptake affinity constant of 3.7 × 10−5 ± 3.1 × 10−6 kg COD m−3. The improved calculation of homoacetogenic kinetics by our approach could correct the underestimation of homoacetogenesis in anaerobic fermentation processes, as it often occurs in these systems supported by literature analysis. The model predictions match the experimental results in different cases well and provide insights into the dynamics of anaerobic glucose conversion and acetate production. Furthermore, acetate production via homoacetogenesis increases by about 40% through utilizing the fed‐batch coupling system, attributed to a balance between the hydrogen production in the acetogenesis phase and the hydrogen consumption in the homoacetogenesis phase. This work provides an effective way for increased anaerobic acetate production, and gives us a better understanding about the homoacetogenic kinetics in the anaerobic fermentation process.

Aggregation of bovine anterior cruciate ligament fibroblasts or marrow stromal cells promotes aggrecan production
Authors: Lim Jeremy J. , Scott Larry , Temenoff Johnna S.
Published: August 2010

The development of a tissue‐engineered alternative for current ligament grafts requires the creation of a fibrocartilaginous interface between the engineered ligament midsubstance and bone tissue. Therefore, the focus of this study was to examine the potential for cartilaginous extracellular matrix (ECM) formation by altering culture parameters for bovine anterior cruciate ligament (ACL) fibroblasts and marrow stromal cells (MSCs). Specifically, cells were cultured without chondrogenic media supplements on aggrecan‐coated surfaces, tissue culture‐treated control surfaces, and nonadhesive surfaces that promoted cell aggregation, and examined over 14 days. Aggrecan‐coated surfaces promoted the aggregation of ACL fibroblasts and MSCs within 24 h after seeding. Aggrecan gene expression was significantly upregulated in cell aggregates, regardless of how cell clustering was induced, with as much as 10.9 ± 1.2‐fold upregulation in ACL fibroblasts and 9.7 ± 1.1‐fold in MSCs after 3 days, compared to control surfaces. Dimethylmethylene blue (DMMB) results and immunostaining verified the presence of aggrecan in ACL fibroblast and MSC aggregates throughout the culture period. Results indicate that ACL fibroblasts retained the ability to alter their gene expression and produce aggrecan, though MSCs, in general, had a more consistent response to aggregation. These findings support the use of aggregate‐inducing materials to encourage production of aggrecan and suggest that altering the degree of clustering could produce a range of phenotypes from a single cell source. As such, this represents a first step which may inform future approaches to producing tissue‐engineered ligament grafts. Biotechnol. Bioeng. 2011; 108:151–162. © 2010 Wiley Periodicals, Inc.
Intraoperative hyperthermic intraperitoneal chemotherapy after cytoreductive surgery for peritoneal carcinomatosis in an experimental model
Authors: Klaver Y L B , Hendriks T , Lomme R M L M , Rutten H J T , Bleichrodt R P , de Hingh I H J T
Published: August 2010

Background

The combination of cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is the treatment of choice for selected patients with peritoneal carcinomatosis (PC) of colorectal origin. However, it remains to be proven whether the addition of HIPEC to CS is essential for the reported survival benefit.

Methods

Sixty WAG/Rij rats were inoculated intraperitoneally with the rat colonic carcinoma cell line CC-531. Animals were randomized into three treatment groups: CS alone, CS followed by HIPEC (mitomycin 15 mg/m2) and CS followed by HIPEC (mitomycin 35 mg/m2). Survival was the primary outcome parameter.

Results

The median survival of rats treated with CS alone was 43 days. Rats receiving HIPEC 15 mg/m2 and HIPEC 35 mg/m2 both had a significantly longer median survival of 75 days (P = 0·003) and 97 days (P < 0·001) respectively. Rats receiving HIPEC showed a significantly lower tumour load at autopsy compared with rats treated with CS alone.

Conclusion

A combination of CS and HIPEC results in longer survival than CS alone in rats with PC of colorectal origin.
A Unified Strategy Targeting the Thiodiketopiperazine Mycotoxins Exserohilone, Gliotoxin, the Epicoccins, the Epicorazines, Rostratin A and Aranotin
Authors: Gross Ulrike , Nieger Martin , Bräse Stefan
Published: August 2010

A unified synthetic strategy directed towards mycotoxins belonging to the thiodiketopiperazine family is reported. The building blocks for a number of natural products—including exserohilone, gliotoxin, the epicoccins, the epicorazines, rostratin A and aranotin—have been synthesised stereoselectively from a common precursor. This key intermediate was constructed through an efficient and highly diastereoselective [2+2] cycloaddition between a ketene and an enecarbamate derived from L‐pyroglutamic acid. The annelation of the second ring was accomplished through ring‐closing metathesis and enol ether–olefin ring‐closing metathesis to provide both cis‐ and trans‐annelated azabicyclic cyclohexenones, as well as an annelated seven‐membered cyclic enol ether. A Pd‐catalysed elimination of allyl acetate gave rise to the cyclohexadienol structure of gliotoxin. Dimerisation of one building block to afford the diketopiperazine core was demonstrated.
Mechanical Properties of Dense Zeolitic Imidazolate Frameworks (ZIFs): A High‐Pressure X‐ray Diffraction, Nanoindentation and Computational Study of the Zinc Framework Zn(Im)2, and its LithiumBoron Analogue, LiB(Im)4

The dense, anhydrous zeolitic imidazolate frameworks (ZIFs), Zn(Im)2 (1) and LiB(Im)4 (2), adopt the same zni topology and differ only in terms of the inorganic species present in their structures. Their mechanical properties (specifically the Young’s and bulk moduli, along with the hardness) have been elucidated by using high pressure, synchrotron X‐ray diffraction, density functional calculations and nanoindentation studies. Under hydrostatic pressure, framework 2 undergoes a phase transition at 1.69 GPa, which is somewhat higher than the transition previously reported in 1. The Young’s modulus (E) and hardness (H) of 1 (E≈8.5, H≈1 GPa) is substantially higher than that of 2 (E≈3, H≈0.1 GPa), whilst its bulk modulus is relatively lower (≈14 GPa cf. ≈16.6 GPa). The heavier, zinc‐containing material was also found to be significantly harder than its light analogue. The differential behaviour of the two materials is discussed in terms of the smaller pore volume of 2 and the greater flexibility of the LiN4 tetrathedron compared with the ZnN4 and BN4 units.

A cyclic free‐base porphyrin dimer H4‐CPDPy (CPD=cyclic porphyrin dimer) linked by butadiyne moieties bearing 4‐pyridyl groups self‐assembles to form a novel porphyrin nanotube in the crystalline state. The cyclic molecules link together through nonclassical CH⋅⋅⋅N hydrogen bonds and π–π interactions of the pyridyl groups along the crystallographic a axis. H4‐CPDPy includes a C60 molecule in its cavity in solution. In the crystal structure of the inclusion complex (C60⊂H4‐CPDPy), the dimer “bites” a C60 molecule by tilting the porphyrin rings with respect to each other, and there are strong π–π interactions between the porphyrin rings and C60. The included C60 molecules form a zigzag chain along the crystallographic b axis through van der Waals contacts with each other. Femtosecond laser flash photolysis of C60⊂H4‐CPDPy in the solid state with photoexcitation at 420 nm shows the formation of a completely charge‐separated state {H4‐CPDPy.++C60.−}, which decays with a lifetime of 470 ps to the ground state. The charge‐carrier mobility of the single crystal of C60⊂H4‐CPDPy was determined by flash photolysis time‐resolved microwave conductivity (FP‐TRMC) measurements. C60⊂H4‐CPDPy has an anisotropic charge mobility (Σμ=0.16 and 0.13 cm2 V−1 s−1) along the zigzag chain of C60 (which runs at 45° and parallel to the crystallographic b axis). To construct a photoelectrochemical cell, C60⊂H4‐CPDPy was deposited onto nanostructured SnO2 films on a transparent electrode. The solar cell exhibited photovoltaic activity with an incident photon to current conversion efficiency of 17 %.
