An Efficient Bulk‐Heterojunction Photovoltaic Cell Based on Energy Transfer in Graded‐Bandgap Polymers
Authors: Gupta D. , Kabra D. , Kolishetti N. , Ramakrishnan S. , Narayan K. S.
Published: December 2006

It is demonstrated that the energy transfer from low‐conjugated (LC) poly[2‐methoxy‐5‐(2‐ethylhexyloxy)‐1,4‐phenylene vinylene] (MEHPPV) to high‐conjugated (HC) MEHPPV, coupled with significant electron transfer from HC‐MEHPPV to an acceptor species, offers a viable route for an efficient photodiode over a wide spectral range. An enhanced incident‐photon‐to‐current conversion efficiency (IPCE) of 19 % over a wide spectral range and a power‐conversion efficiency (ηP) of 1 % (under monochromatic illumination at λ ∼ 530 nm and a power density of ca. 1 mW cm–2) are achieved in a ternary polymer‐blend film that consists of HC‐MEHPPV (low bandgap), LC‐MEHPPV (high bandgap), and an acceptor polymer, cyanoPPV (CNPPV), in an optimized ratio. The decisive role of the morphology that emerges during phase separation in the polymer blend is demonstrated by wide‐field photocurrent imaging.
Effect of Nanotube Functionalization on the Coefficient of Thermal Expansion of Nanocomposites
Authors: Wang S. , Liang Z. , Gonnet P. , Liao Y.‐H. , Wang B. , Zhang C.
Published: December 2006

Single‐walled carbon nanotubes (SWNTs) are functionalized through both covalent and noncovalent bonding approaches to enhance dispersion and interfacial bonding. The coefficient of thermal expansion (CTE) of the functionalized‐SWNT‐reinforced epoxy composites are measured with a thermal mechanical analyzer (TMA). Experimental results indicate that changes of the glass‐transition temperature (Tg) in functionalized SWNT–polymer composites are dependent upon the functionalization methods. The CTE below the glass‐transition temperature of nanocomposites with a 1 wt % loading of nanotubes is substantially diminished compared to a neat polymer. A reduction in the CTE of up to 52 % is observed for nanocomposites using functionalized nanotubes. However, the CTE above the Tg significantly increases because of the contribution from phonon mode and Brownian motions of a large number of SWNTs in resin‐crosslinked networks, but the increments are compromised by possible interfacial confinement. A tunable CTE induced through nanotube functionalization has application potentials for high‐performance composites, intelligent materials, and circuit protections.

Authors: Rice R. L. , Arnold D. C. , Shaw M. T. , Iacopina D. , Quinn A. J. , Amenitsch H. , Holmes J. D. , Morris M. A.
Published: December 2006

Mesoporous thin films are prepared using a simple sol–gel technique. Using lithographically patterned (100)‐orientated substrates and a dip‐coating method reproducible alignment of the pores across the substrate surface can be obtained. The pores preferentially align parallel to the long side of the channels etched into the surface. The channels within the aligned films are subsequently filled with cobalt (to form nanowire‐type structures) using a supercritical fluid inclusion technique, to allow high‐resolution imaging of the pore by using secondary electron microscopy. The channel structure imposes a strain on the mesoporous arrangement resulting in some variation in d‐spacings compared to simple films. The results indicate that the topographic structure can be used to engineer the placement and directionality of the pore structure and the potential of the aligned mesostructures are discussed.
Inside Front Cover: Self‐Assembly of Diblock‐Copolymer Micelles for Template‐Based Preparation of PbTiO3 Nanograins (Adv. Funct. Mater. 18/2006)
Authors: Kronholz S. , Rathgeber S. , Karthäuser S. , Kohlstedt H. , Clemens S. , Schneller T.
Published: December 2006

A bottom‐up fabrication route for PbTiO3 nanograins with dimensions of 30 nm, based on predefined TiO2 nanostructures, is presented on p. 2346 by Karthäuser, Rathgeber, and co‐workers. The patterning of the TiO2 seeds was performed by means of a self‐organized micellar monofilm used as an etching template. The dimensions of the micelle template are transferred across all process steps to the final PbTiO3 nanograins.

A bottom‐up fabrication route for PbTiO3 nanograins grown on predefined TiO2 nanostructures used as seeds is presented. The structuring of the TiO2 seeds is performed using a self‐organized template constructed from a gold‐loaded micellar monofilm. With this fabrication process, TiO2 seeds and PbTiO3 grains with diameters of 12 and 30 nm, respectively, are prepared without the need for electron‐beam lithography. The dimensions of the structure imposed by the micellar template are transferred through all the processing steps to the final PbTiO3 grains. Furthermore, it is shown that the intermicelle distance and the degree of order in the dried monofilm is mainly determined by the preparation conditions, such as the pulling velocity in the dipping process and the strength of the surface–micelle interaction, and not necessarily by the architectural properties (block length and ratio) of the diblock copolymers that build the micelles. The intermicelle spacing in the dried film is much smaller than the micelle dimensions in solution, and approaches the dimensions of a fully collapsed micelle when the dipping process is performed slowly enough.
Tunable Wettability by Clicking Counterions Into Polyelectrolyte Brushes
Authors: Azzaroni O. , Brown A. A. , Huck W. T. S.
Published: December 2006

Polymer brushes have recently emerged as an extremely versatile way to modify surface properties in a robust and controlled way. The introduction of responsive polymers and block copolymers in polymer‐brush systems has also opened up new routes to ‘smart' surfaces with switchable surface properties. Here, the use of polyelectrolyte brushes as a supramolecular platform for the immobilization of a wide range of species, leading to a tunable wettability of substrates, is presented.
Relationship between composition and properties for stable chitosan films containing lipid microdomains
Authors: Grant J. , Tomba J. P. , Lee H. , Allen C.
Published: December 2006

Biocompatible, biodegradable films composed of a hybrid blend of chitosan and egg phosphatidylcholine (ePC) were characterized in terms of composition, morphology, and performance‐related properties. The miscibility between chitosan and ePC for blends of 1 : 0.2 to 1 : 2.5 chitosan : ePC (wt/wt) was examined by differential scanning calorimetry and X‐ray diffraction analysis. The partial miscibility exhibited between chitosan and ePC provided an understanding of the microdomain morphology that was visualized by laser scanning confocal fluorescence microscopy of the films. The stability of the films in physiologically relevant media was assessed by percent weight loss over time. The mechanical properties of the chitosan–ePC films were determined by dynamic mechanical analysis and tensile tests. Interestingly, the dry film composed of a high lipid formulation (1 : 2.5 (wt/wt) chitosan: ePC) had the lowest tensile strength, contained lipid microdomains (10–30 μm in size), and provided the highest degree of stability. Following immersion in phosphate buffer solution, the Young's modulus of the film was found to decrease by more than two orders of magnitude and could be further manipulated by decreasing the lipid content within the film. In this way, relationships between the composition and the physical as well as mechanical properties of the chitosan–ePC blends were established. Furthermore, this study demonstrates the potential usefulness of partially miscible chitosan‐based blends for biomedical purposes. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 3453–3460, 2007
Polymerization kinetics of methylmethacrylate by oxidation: Reduction system using cerium(IV)/lactic acid in aqueous medium
Authors: Demappa Mahadevaiah T.
Published: December 2006

The kinetics of polymerization of methylmethacrylate initiated by cerium(IV)–lactic acid redox system was studied in an aqueous medium in the temperature range of 25–50°C. The rate of polymerization (Rp) and the rate of cerium(IV) disappearance have been measured. The effects of some water‐miscible organic solvents, cationic, anionic, nonionic surfactants, and complexing agents on the rate of polymerization were investigated. The temperature dependence of the rate was studied, and the activation parameters were computed using the Arrhenius and Eyring plots. The effects of inorganic and organic solvents on polymerization were also investigated. All of them depressed both the initial rate and limiting conversion. A mechanism consistent with the experimental data, involving cerium(IV)–lactic acid complex formation, which generates free radicals, is suggested. The chain termination step of the polymerization reaction is by mutual interaction of the growing macromolecules. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 3498–3505, 2007
Studies on xanthate/dithiocarbamate accelerator combination in NR/BR blends
Authors: Palaty Shiny , Joseph Rani
Published: December 2006

Zinc butyl xanthate [Zn(bxt)2] was prepared in the laboratory. The effect of this xanthate with zinc diethyl dithiocarbamate (ZDC) on the vulcanization of natural rubber (NR), polybutadiene rubber (BR), and NR/BR blend has been studied at different temperatures. The amounts of Zn (bxt)2 and ZDC in the compounds were optimized by varying the amount of ZDC from 0.75 to 1.5 phr and Zn (bxt)2 from 0.75 to 1.5 phr. The cure characteristics were also studied. HAF filled NR, BR, and NR/BR blend compounds were cured at different temperatures from 60 to 150°C. The sheets were molded and properties such as tensile strength, tear strength, crosslink density and elongation at break, compression set, abrasion resistance, etc. were evaluated. The results show that the mechanical properties of 80NR/20BR blends are closer to that of NR vulcanizates, properties of 60NR/40BR blends are closer to BR vulcanizates, while the 70NR/30BR blends show an intermediate property. © 2006 Wiley Periodicals, Inc.

Synthesis and Bioimaging of Positron‐Emitting 15O‐Labeled 2‐Deoxy‐D‐glucose of Two‐Minute Half‐Life
Authors: Yorimitsu Hideki , Murakami Yoshihiro , Takamatsu Hiroyuki , Nishimura Shintaro , Nakamura Eiichi
Published: December 2006

In positron emission tomography (PET), which exploits the affinity of a radiopharmaceutical for the target organ, a systematic repertoire of oxygen‐15‐labeled PET tracers is expected to be useful for bioimaging owing to the ubiquity of oxygen atoms in organic compounds. However, because of the 2‐min half‐life of 15O, the synthesis of complex biologically active 15O‐labeled organic molecules has not yet been achieved. A state‐of‐the‐art synthesis now makes available an 15O‐labeled complex organic molecule, 6‐[15O]‐2‐deoxy‐D‐glucose. Ultrarapid radical hydroxylation of 2,6‐dideoxy‐6‐iodo‐D‐glucose with molecular oxygen labeled with 15O of two‐minute half‐life provided the target 15O‐labeled molecule. The labeling reaction with 15O was complete in 1.3 min, and the entire operation time starting from the generation of 15O‐containing dioxygen by a cyclotron to the purification of the labeled sugar was 7 min. The labeled sugar accumulated in the metabolically active organs as well as in the bladder of mice and rats. 15O‐labeling offers the possibility of repetitive scanning and the use of multiple PET tracers in the same body within a short time, and hence should significantly expand the scope of PET studies of small animals.
Structural and Magnetic Study of N2, NO, NO2, and SO2 Adsorbed within a Flexible Single‐Crystal Adsorbent of [Rh2(bza)4(pyz)]n
Authors: Kachi‐Terajima Chihiro , Akatsuka Takamasa , Kohbara Masa‐aki , Takamizawa Satoshi
Published: December 2006

The crystalline one‐dimensional compound, [RhII2(bza)4(pyz)]n (1) (bza=benzoate, pyz=pyrazine) demonstrates gas adsorbency for N2, NO, NO2, and SO2. These gas‐inclusion crystal structures were characterized by single‐crystal X‐ray crystallography as 1⋅1.5 N2 (298 K), 1⋅2.5 N2 (90 K), and 1⋅1.95 NO (90 K) under forcible adsorption conditions and 1⋅2 NO2 (90 K) and 1⋅3 SO2 (90 K) under ambient pressure. Crystal‐phase transition to the P$\bar 1$ space group that correlates with gas adsorption was observed under N2, NO, and SO2 conditions. The C2/c space group was observed under NO2 conditions without phase transition. All adsorbed gases were stabilized by the host lattice. In the N2, NO, and SO2 inclusion crystals at 90 K, short interatomic distances within van der Waals contacts were found among the neighboring guest molecules along the channel. The adsorbed NO molecules generated the trans‐NO⋅⋅⋅NO associated dimer with short intermolecular contacts but without the conventional chemical bond. The magnetic susceptibility of the NO inclusion crystal indicated antiferromagnetic interaction between the NO molecules and paramagnetism arising from the NO monomer. The NO2 inclusion crystal structure revealed that the gas molecules were adsorbed in the crystal in dimeric form, N2O4.
DNA Base Trimers: Empirical and Quantum Chemical Ab Initio Calculations versus Experiment in Vacuo
Authors: Kabeláč Martin , Sherer Edward C. , Cramer Christopher J. , Hobza Pavel
Published: December 2006

A complete scan of the potential‐energy surfaces for selected DNA base trimers has been performed by a molecular dynamics/quenching technique using the force field of Cornell et al. implemented in the AMBER7 program. The resulting most stable/populated structures were then reoptimized at a correlated ab initio level by employing resolution of the identity, Møller–Plesset second‐order perturbation theory (RI‐MP2). A systematic study of these trimers at such a complete level of electronic structure theory is presented for the first time. We show that prior experimental and theoretical interpretations were incorrect in assuming that the most stable structures of the methylated trimers corresponded to planar systems characterized by cyclic intermolecular hydrogen bonding. We found that stacked structures of two bases with the third base in a T‐shape arrangement are the global minima in all of the methylated systems: they are more stable than the cyclic planar structures by about 10 kcal mol−1. The different behaviors of nonmethylated and methylated trimers is also discussed. The high‐level geometries and interaction energies computed for the trimers serve also as a reference for the testing of recently developed density functional theory (DFT) functionals with respect to their ability to correctly describe the balance between the electrostatic and dispersion contributions that bind these trimers together. The recently reported M052X functional with a polarized triple‐zeta basis set predicts 11 uracil trimer interaction energies with a root‐mean‐square error of 2.3 kcal mol−1 relative to highly correlated ab initio theoretical calculations.
Crystallographic and Chiroptical Studies on Tetraarylferrocenes for Use as Chiral Rotary Modules for Molecular Machines
Authors: Muraoka Takahiro , Kinbara Kazushi , Wakamiya Atsushi , Yamaguchi Shigehiro , Aida Takuzo
Published: December 2006

A crystal structure of the racemic form of chiral molecular scissors 1 with a trans configuration at the azobenzene unit (rac‐trans‐1), in which the scissors adopt a closed geometry with two blade phenyl groups that overlap each other, was successfully determined. X‐ray crystallographic determination of the structure of (1S,1′S)‐10, which is a derivative of the key precursor of trans‐1, was also successful. On the basis of the crystal structure of (1S,1′S)‐10, the absolute configuration of 1 and related molecular machines, such as molecular pedal 2, and self‐locking rotor 3, which all contain a chiral tetrasubstituted ferrocene module, were determined. A correlation between the absolute configuration and the circular dichroism properties of these molecular machines and their synthetic precursors was also determined.
