Abstract

Zinc complexes of tetrabenzoporphyrin with mono-, di-, tri-, and tetraphenyl substituents at meso-position show electronic spectra with progressive red shifts from those of tetrabenzoporphyrin zinc complex, and these shifts may be related to ruffling of the macrocycle revealed by crystal structure determination. Fluorescence emissions and basicities of these compounds are also effected by this nonplanarity.
