D-D-[small pi]-A Organic Dyes Containing 4,4[prime or minute]-Di(2-thienyl)triphenylamine Moiety for Efficient Dye-Sensitized Solar Cells

15-Nov-2012 | Mingdao Zhang; Haixian Xie; Xuehai Ju; Ling Qin; Qingxiang Yang; Hegen Zheng; X-F Zhou, Physical Chemistry Chemical Physics, 2012

Dye-sensitized solar cells (DSSCs) are currently under intense academic and industrial investigations, because of their environmentally-friendly, efficient, and low-cost features. Photosensitizer plays as a key role in determining DSSCs’ performance. 4,4′-Di(2-thienyl)triphenylamine moiety, ...

A nucleic acid probe labeled with desmethyl thiazole orange: A new type of hybridization-sensitive fluorescent oligonucleotide for live-cell RNA imaging

15-Nov-2012 | Akimitsu Okamoto; Kaori Sugizaki; Mizue Yuki; Hiroyuki Yanagisawa; Shuji Ikeda; Takuma Sueoka; Gosuke Hayashi; Dan O ..., Organic & Biomolecular Chemistry, 2012

A new fluorescent nucleotide with desmethyl thiazole orange dyes, D’505, has been developed for expansion of the function of fluorescent probes for live-cell RNA imaging. The nucleoside unit of D’505 for DNA autosynthesis was soluble in organic solvents, which made the preparation of nucleoside ...

Lysine‐directed staining of proteins for mass spectrometry‐based analyses

14-Nov-2012 | Matthew T. Yasui, Marco A. Mata‐Gómez, Robert Winkler, ELECTROPHORESIS, 2012

Visualization of proteins and mass spectrometry (MS) based analyses are elemental tasks in modern biochemistry. Nevertheless, reports about covalent protein dyes and their suitability for subsequent MS experiments remain scarce. In a recent work we demonstrated that covalent pre‐staining of ...

Cobalt Electrolyte/Dye Interactions in Dye-Sensitized Solar Cells: A Combined Computational and Experimental Study

14-Nov-2012 | Edoardo Mosconi; Jun-Ho Yum; Florian Kessler; Carlos J. Gómez García; Cristiano Zuccaccia; Antonio Cinti; Mohammad K ..., Journal of the American Chemical Society, 2012

We report a combined experimental and computational investigation to understand the nature of the interactions between cobalt redox mediators and TiO2 surfaces sensitized by ruthenium and organic dyes, and their impact on the performance of the corresponding dye-sensitized solar cells (DSSCs). We ...

Change of Boron Substitution Improves the Lasing Performance of Bodipy Dyes: A Mechanistic Rationalisation

13-Nov-2012 | Krishna K. Jagtap, Neelam Shivran, Soumyaditya Mula, Devidas B. Naik, Sisir K. Sarkar, Tulsi Mukherjee, Dilip K. Mai ..., Chemistry - A European Journal, 2012

Abstract Bodipy laser dyes are highly efficient but degrade rapidly in solution by reacting with in situ generated singlet oxygen (1O2). To increase the lasing lifetimes of these dyes, we have designed and synthesised two different congeners of the widely studied Pyrromethene 567 (PM567) by ...

Photochemical conversion of AgCl nanocubes to hybrid AgCl–Ag nanoparticles with high activity and long-term stability towards photocatalytic degradation of organic dyes

12-Nov-2012 | Jizhuang Wang, Changhua An, Meiyu Zhang, Chuan Qin, Xijuan Ming, Qinhui Zhang, Canadian Journal of Chemistry, 2012

La performance d’une réaction photocatalytique est déterminée principalement par la qualité du photocatalyseur. Pour des applications réelles, l’augmentation significative de la stabilité et de l’activité du photocatalyseur reste le défi à surmonter pour les scientifiques et les chimistes. Dans ...

Solvatochromism and Nonradiative Decay of Intramolecular Charge‐Transfer Excited States: Bands‐of‐Energy Model, Thermodynamics, and Self‐Organization

09-Nov-2012 | Vladimir S. Pavlovich, ChemPhysChem, 2012

Abstract The fluctuations of orientation and induction interactions in solution and their impact on the broadening of absorption and fluorescence spectra are considered in terms of a bands‐of‐energy model. Also covered is the application of principles of thermodynamics and self‐organization of ...

Self‐Assembled Bilayer Films of Ruthenium(II)/Polypyridyl Complexes through Layer‐by‐Layer Deposition on Nanostructured Metal Oxides

09-Nov-2012 | Kenneth Hanson, Daniel A. Torelli, Aaron K. Vannucci, M. Kyle Brennaman, Hanlin Luo, Leila Alibabaei, Wenjing Song, ..., Angewandte Chemie International Edition, 2012

Simple assembly: A “layer‐by‐layer” deposition of functionalized dyes/catalysts on the surfaces of nanocrystalline oxides is introduced. The strategy is general and offers considerable flexibility based on phosphonate‐ or carboxylate‐binding groups with ZrIV as bridging ions. The resulting ...

Carrier transport and charge transfer properties in coumarin‐doped bulk‐heterojunction materials

09-Nov-2012 | T. Watanabe, T. Maeda, K. Yamashita, H. Yanagi, physica status solidi (c), 2012

Abstract We have investigated photovoltaic properties of organic solar cells using polymer‐fullerene bulk‐heterojunction films doped with coumarin dyes. Whereas the coumarin molecules used in this study had similar absorption bands, evident difference was observed in the open‐circuit voltage ...

Synthesis of Novel Biocompatible Composite Fe3O4/ZrO2/Chitosan and Its Application for Dye Removal

09-Nov-2012 | Hualin Jiang, Pinghua Chen, Shenglian Luo, Xubiao Luo, Xinman Tu, Qun Cao, Yanlei Zhou, Weibo Zhang, Journal of Inorganic and Organometallic Polymers and Materials, 2012

A novel biocompatible composite Fe3O4/ZrO2/chitosan was synthesized in a simple way and its capacity of dye removal was investigated in this study. The morphology of the material was examined by SEM and TEM and found to be nanosized and spheroidal. Equilibrium adsorption isotherms and dynamic ...
