Abstract

Protonation made easy: The formation and crystal structure determination of phthalocyanine protonated at the meso- and isoindole nitrogen atoms (see picture) are achieved by using the free base and a zinc complex of saddle-distorted octaphenylphthalocyanine, respectively. The saddle deformation alters the electronic structure of the phthalocyanine ring and facilitates its protonation.
