Synthesis of novel N-linked porphyrin - Phthalocyanine dyads

Abstract

Equation presented Two types of covalently NH-linked porphyrin- phthalocyanine dyads, connected either through the meso phenyl group or the β-pyrrolic position of the porphyrin, have been synthesized following statistical condensation methodologies for phthalocyanine preparation and palladium-catalyzed amination methods. Photophysical studies have revealed that energy transfer from the porphyrin to the phthalocyanine prevails regardless of linkage. © 2007 American Chemical Society.
