Amaresh Mishra (right) received his Ph.D. degree in 2000 from the Sambalpur University, India, under the coguidance of Prof. G. B. Behera and Prof. R. K. Behera, working on dye-surfactant interactions in microheterogeneous media. He started his postdoctoral research career in 1999 at the University of South Florida, Tampa, and subsequently at the University of Akron, Ohio, working with Prof. G. R. Newkome, where he gained knowledge in the area of supramolecular and dendrimer chemistry. Later, he joined the Tata Institute of Fundamental Research, Mumbai, in 2002 as a Visiting Fellow working with Prof. N. Periasamy, where he was involved in the synthesis and photophysical studies of organic light emitting materials. In 2005, he joined in the group of Prof. Peter Ba ¨uerle, University of Ulm, Germany, as an Alexander von Humboldt Fellow. His present research interests are centered on chemistry of functional oligothiophenes, donor-acceptor-based conjugated dyes, and metal complexes toward applications in solar energy conversion and molecular electronic and photonic devices. Chang-Qi Ma (left) received his bachelor's degree in chemistry from Beijing Normal University in 1998. In 2003 he obtained his Ph.D. degree at the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences in Beijing with Professor B.-W. Zhang. After that he was a postdoctoral research assistant at Heriot-Watt University in Edinburgh, U.K., with Dr. G. Cooke, until he joined the research group of Prof. P. Ba ¨uerle at the University of Ulm in 2004 as an Alexander von Humboldt fellow, where he is currently a research associate. His main research interests focus on the design and synthesis of novel π-conjugated organic materials for the application in organic electronics, e.g. organic solar cells.Peter Ba ¨uerle (center) received his Ph.D. in organic chemistry from University of Stuttgart (Germany, 1985) working with Prof. F. Effenberger. After a postdoctoral year at MIT, Boston, Massachusetts, in the group of Prof. M. S. Wrighton, he carried out independent research at the University of Stuttgart and received his habilitation (1994). After being Professor of Organic Chemistry at the University of Wu ¨rzburg (Germany, 1994-95), he became Director of the Institute for Organic Chemistry II and Advanced Materials at the University of Ulm (Germany, since 1996). Current research interests of the group include development of novel organic semiconducting and conducting materials, in particular, conjugated poly-and oligothiophenes. Synthetic strategies and new reactions for their functionalization, structure-property relationships, self-assembling properties, and applications in electronic devices, in particular organic solar cells, are investigated. Results have been published in about 200 peer-reviewed scientific papers, 3 book chapters, and 7 patents. For his work in the field of plastic electronics he was awarded with the Rene ´Descartes Prize of the European Union (2000). Guest Professorships at the University of Osaka (Japan, 2002), U...

“…Iodination using iodine in the presence of mercuric oxide provided the targets with complete regioselectivity (94-95% yield) at room temperature. [29] However, this protocol required the use of five equivalents of mercuric oxide in benzene, making this an unattractive procedure for large-scale synthesis. In the final cross-coupling procedure, we looked to optimise several variables.…”

“…Dyes FL15 and FL16 were synthesized as shown in Scheme 2, starting from alkyne 1. [5] Sonogashira coupling between 1 and 2-iodothiophene derivatives 2 a (see the Supporting Information) and 2 b [6] afforded aldehydes 3 a and 3 b in 87 and 66 % yield, respectively, after purification by column chromatography. The formation of 3 a and 3 b was confirmed in the 1 H NMR spectra by the presence of an aldehyde signal at d = 9.96 ppm in both cases.…”

The synthesis, full characterization, and use of a series of organic dyes with thienylenevinylene and ethynyl bridges as light-harvesting chromophores in TiO 2 -based photoelectrochemical dye-sensitized solar cells are described. A maximum light-to-energy conversion efficiency of h = 5.47 % under standard conditions is obtained for the organic dye denoted as FL16, which consists of an N,N-bis(4-hexyloxyphenyl)aniline donor moiety, an ethynylthieno[3,2-b]thiophene p bridge, and a 2-cyanoacrylic acid acceptor group. The device properties are investigated by charge extraction and transient photovoltage measurements.
