摘要：
Absorption and emission spectra of the doubly quinone-bridged porphyrin cyclophanes 1 - 4 with gradually varied acceptor strength as well as of the single-bridged analogues 5 - 9 and 10 - 13 are reported. Reduction and oxidation potentials of these intramolecular porphyrin-quinone systems have been determined. Based on these data, fluorescence quenching as well as time-resolved fluorescence lifetime measurements are discussed in terms of photoinduced electron transfer to the change-separated zwitterionic state.
