β-Tetrachlorotetramethoxyporphycenes: positional effect of substituents on structure and photophysical properties

Chem Commun (Camb). 2015 Aug 7;51(61):12239-42. doi: 10.1039/c5cc03867g.

Abstract

We report the regiospecific synthesis of the first chloro-substituted porphycenes as two positional isomers of β-tetrachlorotetramethoxyporphycene. The positional effect of the substituents on these isomers could be clearly distinguished in their structure and photophysical properties.
