Staircase-form assembly with 5,15-bis(imidazol-4-yl)porphinatogallium steps

Abstract

Large supramolecular assemblies of 5,15-bis(imidazol-4-yl)porphinatogallium 2Ga have been synthesized by hexacoordination of two imidazolyl groups to Ga(III) in a staircase arrangement of porphyrin planes as each “step”. The structure of the supramolecular assembly was characterized by UV, X-ray diffraction, and AFM. The conductivity of 2Ga films was enhanced 8 times by photoirradiation.
