1,15-Bis-(2′,2′,4′-trimethyl-3′-pentoxy)phthalocyanine, a trans-form nonperipheral di-substituted phthalocyanine synthesized by the ‘cross condensation’ method

The crystal structure of 1, 15-bis-(2′,2′,4′-trimethyl-3′-pentoxy)phthalocyanine was determined what confirmed the ‘cross condensation’ method for the ABAB type phthalocyanine and the trans-form arrangement of the two substituents suggested that the alkoxy group also affected the condensation mechanism.
