Abstract

We have carried out an experimental and computational study on the ground-and excited- state photochemical and photophysical properties of (1-cyclohexenyl) phenyldiazene (CPD), a species formally derived from azobenzene in which one of the phenyl rings is replaced by a 1-cyclohexene substituent. The results show that CPD does substantially behave like azobenzene, but with a higher (~ 70%) Φ Z→ E (nπ*) photoisomerization quantum yield, ...
