— The results of exploratory and mechanistic studies of the photochemistry of poly‐ p ‐benzoyl‐acetimido‐bovine serum albumin, a modified protein containing photoreactive and photosensitizing groups, are reported. Specifically described are our recent findings concerning (1) the synthesis and characterization of a modified bovine serum albumin that contains benzophenone‐like moieties, (2) the photochemistry of this modified protein which appears to involve photoreductive coupling of the benzophenone chromophores to the protein backbone, and (3) triplet energy transfer from modified bovine serum albumin to small molecule acceptors resulting in quenching of the photoreaction.
