A novel polystyrene with non-symmetrical zinc phthalocyanines as terminal group

A new non-symmetrical zinc(II) phthalocyanine (ZnPc) with an alkynyl functional group was prepared by an efficient mixed statistical condensation of 4-((4-ethynylbenzyl)oxy)phthalonitrile (1) and 4-(4-tert-butylphenoxy)phthalonitrile (2). The isolated unsymmetrical phthalocyanine molecule with additional three 4-tert-butylbenzyloxy groups to maintain solubility was used in the Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition, better known as...
