Description

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.
