Pronounced effects on switching efficiency of diarylcycloalkenes upon cycloalkene ring contraction

Author affiliations

Abstract

Several difurylperfluorocyclobutenes showing reversible photochromism were synthesized. In comparison to their cyclopentene homologues they show enhanced quantum yields for ring opening but reduced quantum yields for ring closure. X-ray structure analysis and quantum chemical calculations provide a conclusive explanation for such a behaviour.
