POLYCYCLIC AROMATIC COMPOUNDS, vol.18, no.2, pp.211-220, 2000 (SCI-Expanded)
Di- and tri- [2(2)]-para-cyclophane fused metal-free tetraazaporpyrins were subjected to AM1 type semiempirical molecular orbital treatment. The calculations predict that they should be stable but endothermic structures. Some quantum chemical and physicochemical properties of them have been presented as well.
