Published: July 2015

AbstractA novel metal‐doping strategy was developed for the construction of iron‐decorated microporous aromatic polymers with high small‐gas‐uptake capacities. Cost‐effective ferrocene‐functionalized microporous aromatic polymers (FMAPs) were constructed by a one‐step Friedel–Crafts reaction of ferrocene and s‐triazine monomers. The introduction of ferrocene endows the microporous polymers with a regular and homogenous dispersion of iron, which avoids the slow reunion that is usually encountered in previously reported metal‐doping procedures, permitting a strong interaction between the porous solid and guest gases. Compared to ferrocene‐free analogues, FMAP‐1, which has a moderate BET surface area, shows good gas‐adsorption capabilities for H2 (1.75 wt % at 77 K/1.0 bar), CH4 (5.5 wt % at 298 K/25.0 bar), and CO2 (16.9 wt % at 273 K/1.0 bar), as well as a remarkably high ideal adsorbed solution theory CO2/N2 selectivity (107 v/v at 273 K/(0–1.0) bar), and high isosteric heats of adsorption of H2 (16.9 kJ mol−1) and CO2 (41.6 kJ mol−1).

AbstractIn molecular imaging, multimodal imaging agents can provide complementary information, for improving the accuracy of disease diagnosis or enhancing patient management. In particular, optical/nuclear imaging may find important preclinical and clinical applications. To simplify the preparation of dual‐labeled imaging agents, we prepared versatile monomolecular multimodal imaging probe (MOMIP) platforms containing both a fluorescent dye (BODIPY) and a metal chelator (polyazamacrocycle). One of the MOMIP was conjugated to a cyclopeptide (i.e., octreotide) and radiolabeled with 111In. In vitro and in vivo studies of the resulting bioconjugate were conducted, highlighting the potential of these BODIPY‐based bimodal probes. This work also confirmed that the biovector and/or the bimodal probes must be chosen carefully, due to the impact of the MOMIP on the overall properties of the resulting imaging agent.

Published: July 2015

AbstractAs the research in nanotechnology progresses, there will eventually be an influx in the number of commercial products containing different types of nanomaterials. This phenomenon might damage our health and environment if the nanomaterials used are found to be toxic and they are released into the waters when the products degrade. In this study, we investigated the cytotoxicity of fluorinated nanocarbons (CXFs), a group of nanomaterials which can find applications in solid lubricants and lithium primary batteries. Our cell viability findings indicated that the toxicological effects induced by the CXF are dependent on the dose, size, shape, and fluorine content of the CXF. In addition, we verified that CXFs have insignificant interactions with the cell viability assays—methylthiazolyldiphenyl‐tetrazolium bromide (MTT) and water‐soluble tetrazolium salt (WST‐8), thus suggesting that the cytotoxicity data obtained are unlikely to be affected by CXF‐induced artifacts and the results will be reliable.
Cyclometalated Iridium(III) Complexes as Two‐Photon Phosphorescent Probes for Specific Mitochondrial Dynamics Tracking in Living Cells

Published: July 2015

AbstractFive cyclometalated iridium(III) complexes with 2‐phenylimidazo[4,5‐f][1,10]phenanthroline derivatives (IrL1–IrL5) were synthesized and developed to image and track mitochondria in living cells under two‐photon (750 nm) excitation, with two‐photon absorption cross‐sections of 48.8–65.5 GM at 750 nm. Confocal microscopy and inductive coupled plasma‐mass spectrometry (ICP‐MS) demonstrated that these complexes selectively accumulate in mitochondria within 5 min, without needing additional reagents for membrane permeabilization, or replacement of the culture medium. In addition, photobleaching experiments and luminescence measurements confirmed the photostability of these complexes under continuous laser irradiation and physiological pH resistance. Moreover, results using 3D multicellular spheroids demonstrate the proficiency of these two‐photon luminescent complexes in deep penetration imaging. Two‐photon excitation using such novel complexes of iridium(III) for exclusive visualization of mitochondria in living cells may substantially enhance practical applications of bioimaging and tracking.
Rational Tuning of the Electrocatalytic Nanobiointerface for a “Turn‐Off” Biofuel‐Cell‐Based Self‐Powered Biosensor for p53 Protein
Authors: Han Yajing , Chabu Johnny Muya , Hu Shengqiang , Deng Liu , Liu You‐Nian , Guo Shaojun 
Published: July 2015

AbstractHerein, a novel tunable electrocatalytic nanobiointerface for the construction of a high‐sensitivity and high‐selectivity biofuel‐cell (BFC)‐based self‐powered biosensor for the detection of transcription factor protein p53 is reported, in which bilirubin oxidase (BOD)/DNA supramolecular modified graphene/platinum nanoparticles hybrid nanosheet (GPNHN) works as a new enhanced material of biocathode to control the attachment of target, and thus tune the electron‐transfer process of oxygen reduction for transducing signaling magnification. It is found that in the presence of p53, the strong interaction between the wild‐type p53 and its consensus DNA sequence on the electrode surface can block the electron transfer from the BOD to the electrode, thus providing a good opportunity for reducing the electrocatalytic activity of oxygen reduction in the biocathode. This in combination with the glucose oxidation at the carbon nanotube/Meldola’s blue/glucose dehydrogenase bioanode can result in a current/or power decrease of BFC in the presence of wild‐type p53. The specially designed BFC‐based self‐powered p53 sensor shows a wide linear range from 1 pM to 1 μM with a detection limit of 1 pM for analyzing wild‐type p53. Most importantly, our BFC‐based self‐powered sensors can detect the concentrations of wild‐type p53 in normal and cancer cell lysates without any extensive sample pretreatment/separation or specialized instruments. The present BFC‐based self‐powered sensor can provide a simple, economical, sensitive, and rapid way for analyzing p53 protein in normal and cancer cells at clinical level, which shows great potential for creating the treatment modalities that capitalize on the concentration variation of the wild‐type p53.

Ionic Liquids as Size‐ and Shape‐Regulating Solvents for the Synthesis of Cobalt Nanoparticles
Authors: Essig Sarah , Behrens Silke 
Published: July 2015

AbstractOver the last few years, ionic liquids (ILs) have emerged as an important class of reaction media for the synthesis of nanoparticles. The formation and stabilization of nanoparticles was investigated in different ILs to elucidate the effect of the chemical nature of the IL anion, cation and alkyl side chain of the imidazolium. In this context, Co2(CO)8 was employed as a precursor and thermally decomposed to the metallic cobalt nanoparticles in a series of selected ILs, where either the IL cation or anion was varied while keeping all of the other parameters constant. The results show that both the molecular volume of the anion and cation and the steric configuration are important aspects to control the formation and stability of nanoparticles in ILs.

Published: July 2015

AbstractA high‐efficient and stereo‐specific approach for the preparation of biologically important (E)‐2‐styryl‐tetrahydrobenzo[d]thiazoles has been developed via TMSCl promoted direct sp3 C‐H alkenylation of 2‐methyl‐5,6‐dihydrobenzo[d]thiazol‐7(4H)‐one under metal‐free conditions. Seventeen target compounds were synthesized in excellent yields of 82% –98% under the optimal conditions of 300 mol% TMSCl at 110°C for 2 h, and their chemical structures were elucidated by IR, NMR, ESI‐MS, elemental analyses and X‐ray crystallography analysis. A plausible mechanism was also proposed, and this method provided a good functional group conversion for the sp3 C‐H substrates.
Preparation of ZSM‐5 Coated on Monolithic Interconnected Macroporous Al2O3 Using Cheap n‐Butylamine as Template
Authors: Sun Mingliang , Zhao Tianbo , Wang Jia , Ma Zhaofei , Li Fengyan 
Published: July 2015

AbstractUsing cheap n‐butylamine as template, ZSM‐5 zeolites have been successfully synthesized and coated on monolithic interconnected macroporous Al2O3 by the secondary growth method. The use of cheap n‐butylamine could significantly reduce the synthesis cost. Hierarchical monolithic ZSM‐5 zeolites were prepared from synthetic mixtures with different H2O/Na2O or SiO2/Al2O3 ratio. The synthesized samples were characterized by scanning electron microscopy (SEM), X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR) and N2 adsorption‐desorption. The results show that the hierarchical monolithic zeolites were obtained with cheap n‐butylamine template as template. During the hydrothermal reaction process, the morphology of the micrometer‐sized support was well maintained. The irregular crystals were formed in a wide range of the H2O/Na2O or SiO2/Al2O3 ratio of synthetic mixtures and coated on monolithic Al2O3. The relative crystallinity of the zeolites was highest at H2O/Na2O=250 or SiO2/Al2O3=160. This type of composites exhibited hierarchical porous structures and relatively high specific surface areas.
