“…492,493 By this synthetic approach, various alkyl-substituted thieno[3,4-b]pyrazines 3.33 were synthesized and chemically polymerized with FeCl 3 . The resulting polymers were highly soluble in organic solvents due to the alkyl side chains and had low band gaps of 0.8-1.1 eV.…”

“…The resulting polymers were highly soluble in organic solvents due to the alkyl side chains and had low band gaps of 0.8-1.1 eV. 458,492,493 There has been no report on successful electrochemical polymerization of thieno [3,4-b]pyrazine derivatives, and a popular hypothesis holds that the failure is due to the quenching of the created radical cations by the pyrazine ring. 494 However, Rasmussen et al indicated that the reason may lie in the monomers' trait of easy overoxidation.…”

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...

“…As outlined in Scheme 2, TPs can be prepared from thiophene in four steps with high overall yields. This has resulted in the preparation of a wide variety of TPs, from the unfunctionalized parent , to a number of 2,3‐dialkylthieno[3,4‐ b ]pyrazines and 2,3‐diarylthieno[3,4‐ b ]pyrazines , and even several asymmetrically substituted examples .…”

“…This feature would allow for orthogonal processing of optoelectronic devices with multi-layered configurations, in which successive layer deposition is required, while keeping the underlying polymer layers intact. [10] Herein, we report the synthesis of a highly fluorinated conjugated polymer, poly-(2,3-bis(perfluorohexyl)thieno[3,4-b]pyrazine) (PPFHTP, Figure 1 a), on the first fluorinated version of poly(thieno-[3,4-b]pyrazine)s (pC n TPs), [11,12] which are low-bandgap polymers. [13] The fluorinated polymer exhibited selective solubility in perfluorinated solvents, high air-and thermal stability, high EA, electrochemical n-doping behavior, and a low bandgap.…”

Ein n‐dotierter polymerer Halbleiter, Poly(2,3‐bis(perfluorohexyl)thieno[3,4‐b]pyrazin), wurde durch Pd‐katalysierte Polykondensation in einem mehrphasigen Lösungsmittelsystem synthetisiert. Dies ist das erste Beispiel für einen n‐dotieren polymeren Halbleiter, der ausschließlich in fluorierten Lösungsmitteln löslich ist. Der Halbleiter wurde zur Fertigung organischer Feldeffekttransistoren genutzt (siehe Bild).
