摘要: The enhanced fluorescence of several 1,3-bichromophoric propanes in aqueous cyclodextrin solutions has been investigated by the steady-state spectra and lifetimes. 1-(9,10-Dicyano-2-anthryl)-3-(1- 2-naphthyl)propanes exhibit intramolecular charge transfer complex generated ground state presence γ-cyclodextrin. Two bichromophoric propanes, 1,3-di-2-naphthylpropane 1-(1-naphthyl)-3-(2-naphthyl)propane, β- γ-cyclodextrin show not only excimer but also fluorescences, though formation dinaphthylpropane never observed homogeneous solution even at low temperature. interactions excited states seem to be attributable their intramolecularly geometrical restriction extraordinary nonpolar cavity cyclodextrins.
