Photochemistry and Spectroscopy of “Stable Organic Radicals”:  Steric and Electronic Effects in Intermolecular Photoinduced Electron Transfer

The intermolecular reactivities of amino-substituted perchlorotriphenylmethyl radicals 1−3 were studied, with particular emphasis on electron transfer (ET) reactions. The natural fluorescence lifetimes and the rates of the electron-transfer quenching were studied with several electron donors and acc...

Description
Summary:The intermolecular reactivities of amino-substituted perchlorotriphenylmethyl radicals 1−3 were studied, with particular emphasis on electron transfer (ET) reactions. The natural fluorescence lifetimes and the rates of the electron-transfer quenching were studied with several electron donors and acceptors. Fluorescence quenching studies demonstrate the importance of the redox potentials of the ET pair on the observed steric and electronic properties.
