Abstract
Photochemically reactive systems have been developed which allow the quantitative assessment of free energy/rate correlations for intramolecular excited state electron and energy transfer (ET and E NT, respectively). Preliminary results are described on systems which contain the (diimine)Re I(CO) 3-chromophore covalently linked to either an electron donor or an (excited state) energy acceptor. The electron donor and the energy acceptor units undergo rapid chemical reaction upon being oxidized (via photoinduced ET) or photochemically excited (by intramolecular E NT). Quantitative examination of the photophysics and photochemical reaction quantum yields in these molecules allows evaluation of the rates of intramolecular ET and E NT.
