Abstract

Upon irradiation a mixed-valence (MV) state is formed in a donor-iridium(III)-acceptor triad by a photoinduced electron transfer process. The resulting radical and intervalence charge transfer (IV-CT) absorptions cover a wide spectral range (3200-400 nm). These results were supported by spectroelectrochemistry, fs-time resolved pump-probe spectroscopy and assisted by TD-DFT calculations.
