Charge-transfer dynamics in organic mixed-valence compounds — •Ingo Fischer — Universität Würzburg, Institut für Physikalische und Theoretische Chemie

Organic mixed-valence (MV) compounds are promising building blocks for application as optoelectronic materials. In these compounds an electron donor and an electron acceptor are connected via a bridge. Electron transfer can be induced by optical excitation and the subsequent back-electron transfer is studied by time-resolved transient absorption on the ps- and fs-time scale. In this talk some general aspects of the work on MV-compounds will be presented and an overwiew on recent experiments in our group will be given. We will discuss in particular the influence of the bridge on the back-electron transfer rate and some aspects of the early-time solvation dynamics.
