Dinuclear Metal Complexes

The synthesis and photophysical properties of heterometallic dinuclear complexes based on ruthenium and osmium trisbipyridine units, Ru-mPh3-Os and Ru-mPh5-Os, in which the metal complexes are linked via an oligophenylene bridge centrally connected in the meta position, are described. Electronic energy transfer from the excited ruthenium-based component (donor) to the osmium moiety (acceptor) has been investigated using steady-state and time-resolved spectroscopy. The results obtained for the meta-substituted compounds are compared with the analogous systems in which the phenylene spacers are substituted in the para position. The mechanism of energy transfer is discussed.

Basic Assumptions

A summary of the main energy transfer (ET) mechanisms between isolated pairs of molecules in solution is presented. Various ET models for many-molecules systems are discussed in their basic assumptions and their range of applicability. Time-resolved studies of ET in solution allow to determine the predominant ET mechanism and to test ET models.
