Abstract

The photochemical reactions of (p-benzoylphenyl) diphenylmethyl (1) and (p- benzoylphenyl) bis (4-tert-butylphenyl) methyl (2) in various solvents were investigated. The photophysical parameters of the first excited doublet state of the radicals were measured using spectroscopic and kinetic methods and led to a “molecular rotor” model to characterize the excited-state behavior. The charge-transfer excited state for both radicals was ...
