“…Ruthenium complexes of phosphin-containing terthiophene ligands 2.320 were synthesized with the aim to prepare oligomers or polymers with redox-switchable hemilabile ligands (Chart 2.52). 392 Interestingly, the ligand that is η 1 -bound to the terminal thiophene was easily displaced when 4 equiv of acetonitrile were added. Spectroelectrochemical investigations of the corresponding electrochemically generated polymer revealed that the ruthenium centers showed a reversible and switchable intramolecular interaction with the polymer backbone.…”

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...

“…Mirkin and coworkers have elegantly demonstrated this concept through the electropolymerization of 24. [43] Oxidation of the polymer film results in a 18 cm ±1 shift in the CO infrared stretching frequency. A gradual increase in the level of backbone oxidation could give rise to a gradual shift in the stretching frequency; however, only two discrete stretching bands are observed during this experiment suggesting that holes are localized along the polymer backbone (Fig.…”

Terthienyl-Based Redox-Switchable Hemilabile Ligands: Transition Metal Polymeric Complexes with Electrochemically Tunable or Switchable Coordination Environments?

Abstract: By controlling the extent of oxidation of the polymeric forms of the new class of isolable, polymerizable terthienyl Ru(II) complexes 1, one can modulate both the binding strength of the polymer backbone for Ru(II) and the electronic nature of the bound metal centers.
