Photo and electro-chemistry of molecular architectures based on coordination complexes

Dr. Jerome Chauvin

University Grenoble Alpes, France

The development of (photo)redox active nanoarchitectures anchored on electrode is of large interest for solar energy conversion or molecular electronic devices. In such applications, transition metal-ligand complexes play an important role, owing to the great diversity of their properties depending on the metal and organic ligands used. In particular the electrochemical and photophysical characteristics of [Ru(bpy)3]2+-based complexes (bpy = 2,2’ bipyridine) have been largely investigated as light harvesting unit for the design of photoresponsive surfaces. A particular design for photo-to-electric conversion is based on the well-ordered association on electrode of a photosensitizer unit with electron donor or acceptor, to funnel under irradiation the charge from or to the conducting surface. In this presentation some examples of well-ordered layers with photoredox properties will be discussed, aiming to understand some of the essential parameters that should be modulated in order to obtain more efficient photo-conversion devices.

Brief Bio:

Jerome Chauvin received his PhD degree in 1998 from Ecole Normale Superieure de Cachan (France) under the supervision of Pr Jacques Delaire and Keitaro Nakatani, working on photochromic materials for application in nonlinear optics. He spent two years as a research fellow in Japan (1999-2001) in the laboratory of Pr Masahiro Irie. In September 2001 he was promoted maître de conférences at University of Grenoble Alpes, where he conducts his research in the field of molecular materials for artificial photosynthesis. Jérôme Chauvin defended his habilitation in 2011, the same year he spent 6 months as a visiting research in the Group of Pr. D. Gust, T. & A. Moore in Arizona State University.
