Abstract

The photosensitized cis/trans isomerization of a series of 1-(1-propeny1) cycloalkenes is reported. A plot of the photostationary state trans/cis ratio vs the sensitizer triplet energy for 1- (1-propeny1) cyclopentene shows a constant trans/cis ratio of-1.0 with high-energy sensitizers (ET> 61 kcal/mol). The plot shows one maxima at ET-55 kcal/mol with low-energy sensitizers (ET C 61 kcal/mol). This type of plot is very similar to those obtained with ...
