The photophysical properties of an oblique bisporphyrin, comprising zinc(II) and gold (III) porphyrins separated by a 2,7-diphenyl-1,10-phenanthroline spacer moiety, have been measured in a low-temperature ethanol glass. Comparison with the propertie

Intramolecular electron-transfer reactions in polymers with aromatic side groups were confirmed by the pulse radiolysis of solutions containing poly(4-vinylbiphenyl-co-1-vinylpyrene). First, the optical absorption spectra and decay reactions of the a

Fluorescence lifetimes were determined for porphyrins linked to quinones at two different fixed distances by bicyclo[2.2.2]octyl spacers. Electron-transfer rate constants for the one- and two-spacer homologues were calculated from the lifetimes. The
