摘 要:Density functional theory method was employed to investigate the electronic properties of two series of sub- porphyrazine and subphthalocyanine derivatives, namely SubPz, SubPz-1H, SubPz-2H, SubPz-3H, SubPc, SubPc-1H, SubPc-2H, and SubPc-3H. Calculated results show that peripheral hydrogenation essentially changes the delocalized pattern from the common π14^14 to limited π13^14 or π12^14 for SubPz series, and substantially weakens the aromaticity for both SubPz and SubPc compounds. The unordinary delocalized circuit owns an unstable energy level, and thus gives rise to a notable transformation of geometric configuration, frontier molecular orbital topology, and absorption spectral bands.Density functional theory method was employed to investigate the electronic properties of two series of sub- porphyrazine and subphthalocyanine derivatives, namely SubPz, SubPz-1H, SubPz-2H, SubPz-3H, SubPc, SubPc-1H, SubPc-2H, and SubPc-3H.
