A zinc gable phthalocyanine and a derived planar bis-phthalocyanine containing a shared anthracene unit

Abstract

A gable-type zinc phthalocyanine and a derived planar bis-phthalocyanine containing a shared anthracene unit have been synthesized and their spectroscopic properties examined. The former showed a split Q band, while the latter exhibited a red-shifted but unsplit Q band, as explained by exciton coupling theory and molecular orbital calculations.
