Abstract: Geometries of a series of chiral binaphthyl bridged bis-porphyrins were optimized at semiempirical AM1 quantum chemistry level.The frontier molecular orbitals and electronic spectra of these chiral bis-porphyrins obtained by the ZINDO/S method suggested that the charge-transfer of chiral bis-porphyrins was multidimensional and appeared between the conjugated system of binaphthyl and porphyrin.The ability of donor was enhanced and the λmax values were decreased by introducing ample-electron heterocyclics.
