Functional Interfaces

We present a spectroscopic study of the photoinduced excited-state processes in new materials for polymer solar cells and organic-light emitting diodes, which are based on extended conjugated terpyridine systems. Various spectroscopic tools were combined to investigate the photoinduced dynamics in such systems from the Franck-Condon point up to nanoseconds after light-absorption. The intriguing finding of dual luminescence from a novel class of terpyridine complexes are discussed
