摘要：

AM1 and MNDO were used to optimize supermolecular structures of cyclobis (paraquat-p-phenylene) to neutral guests and obtain DeltaDeltaE for interchanging of complexes. Electronic spectra of four complexes were calculated with INDO/SCI based on AMI geometries, and it was indicated that their characteristic absorption peaks are red-shifted compared with those of the host or the guests. Meanwhile the potential curve in the presence of H+ for the complex of the host and the biphenyl ether derivative was computed with AMI and the mechanism of the "on-off" switching was discussed.
