Bridged polymeric phthalocyanines exist in different isomeric forms of varying symmetry. The number of isomers and the symmetry depends on the structure, i. e. the size and shape, of the polymeric phthalocyanine. Equations are derived for calculating the number of isomers for bridged polymeric phthalocyanines, and symmetry point groups for various shapes (linear, square, rectangular) are discussed.
