  2. 1. Porphyrin-Based Donor-Bridge-Acceptor Systems: Intrinsic Excited State Deactivation and Intramolecular Energy/Electron Transfer Reactions

    Author : Joakim Andreasson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectroscopy; superexchange; mediation; energy transfer; porphyrins; conformational gating; conformational distortions; electron transfer;

    Abstract : Intramolecular energy and electron transfer reactions have been studied between porphyrin donor and acceptor moieties. The porphyrin units are covalently linked together by one of three different bridging chromophores to constitute the series of D-B-A systems. READ MORE
