Abstract

The synthesis and characterization of a subphthalocyanine–azobenzene–subphthalocyanine triad is reported. Evidence for trans ↔ cis isomerization of the linking azobenzene moiety is observed in the NMR and optical spectra when the subphthalocyanine rings are used as light-harvesting units. Significantly, a decrease in fluorescence intensity is observed on moving from trans → cis with a recovery in intensity observed on moving back from cis → trans that can be attributed to a change in the rate of non-radiative decay.
