ISOMERISM AND SYMMETRY OF BRIDGED POLYMERIC PHTHALOCYANINES

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