Abstract

Substitution of a 2-anthryl group at the nitrogen of N=NPh and N=CHPh bonds led to mutual isomerization between Z and E isomers on triplet sensitization giving photostationary mixtures very much rich in E isomers, although the substitution at the carbon of CH=NPh bond resulted in one-way Z → E isomerization in the triplet state likewise to CH=CHPh and C(CH3)=NOCH3 bonds.
