Sažetak

Porphinoid, both existing and hypothetical systems, are represented
by graphs at the nearest-neighbour level of approximation.
By dimer covering of these graphs characteristic and reference
polynomials are obtained and the topological resonance energy is
calculated. It has been found that aromatic stabilization of porphins
is mainly due to the high topological resonance energy value of
pyrrole-type rings, while aromatic stabilization of phthalocyanins
is due mainly to high resonance stabilization of i-indole-type rings.
