摘 要：Optically active binaphthyl units have been introduced onto the periphery of the phthalocyanine chormophores in the phthalocyanine-porphyrin-fused oligomers,resulting in the first（R）-and（S）-enantiomers of Pc-Por-fused dimer and trimer with induced chirality *** represents the largest chiral tetrapyrrole-based conjugated system,to the best of our *** absorption,MCD,and CD spectroscopic results in combination with theoretical calculations disclose the effective transfer of the chiral information from the binaphthyl groups to both the central tetrapyrrole-fused chromophores,indicating the effective delocalization of the π-electron density over the fused systems due to the effective electronic communication between/among the tetrapyrrole chromophores.
