Abstract

The goal of the present study is a better understanding of photoinduced electron or energy transfer in a single molecule. The growing interest of this field is caused by its implication in life phenomena such as photosynthesis and in the development of molecular devices. We present molecular design of new compounds consisting of a well-known luminescent organic moiety (porphyrin, carbazole, phthalocyanine) bound to an inorganic one by a bridging ligand. This latter is in the simplest case a triple bond that can be extended easily. In the present work, the inorganic part is a pentaammine—ruthenium which has been extensively studied previously. Our interest is focused on the possible ability of the ruthenium moiety to quench the light emission of the luminescent organic chromophore.
