✦ Synopsis

Abstract

The number of isomers i~r,t~ for stacked polymeric phthalocyanines in which each phthalocyanine ring is tetrasubstituted or octasubstituted with two different substituents (each benzene moiety substituted with both substitutents) is determined to be

where m is the number of substituted phthalonitrile molecules incorporated into the polymer and x is the number of phthalocyanine macrocycles (degree of polymerization; m = 4__x__). Specifically, for a stacked polymeric phthalocyanine with x = 2; there exist 298 isomers. The stacked polymeric phthalocyanines with substituted phthalocyanine rings possess different symmetry groups (D~2h~, D~2d~, C~4~, C~2V~ or C~S~ E as sole symmetry operation). The results are valid for stacking of other macrocycles similar to phthalocyanine such as prophyrins.
