摘要：

New pheophorbide-quinone derivatives with a different kind of quinone moieties were synthesized by mixed anhydride method. The structures of these compounds were confirmed by UV, IR, 1HNMR, fluorescence, and mass spectra. Effective fluorescence quenching of the pheophorbide chromophores in the synthesized molecules was observed depending on the electron-accepting properties of the quinone fragment and spatial disposition of the donor and acceptor. Electron-transfer rate constants were calculated based on fluorescence decay measurements. The role of energetic and conformational changes of pheophorbide-quinones in the electron-transfer processes is discussed.
