Abstract: Single chain benzalaniline containing ammonium amphiphiles formed vesicle bilayers in the aqueous solution. Being a kind of chromphore,the benzalaniline group embeded in amphiphiles is active for absorption and fluorescence, No very strong excitation and emission intensities were determined in ethanol dispersion, but the phenomenon was found in the aqueous solution,that is tight aggregation of bimolecular layer induced fluorescence enhancing.The reason is that the tight aggregation made the molecule arrangement orderly so that little excitation energy was exhausted by nonradiative transfers such as thermal collision, conformation divert and so on.This process is very favorable for energy transfer because it was not observed in liquid crystal state and in ethanol dispersion.The result reveals that more orderly arrangement of amphiphiles in bilayers is benefit to controlling energy transfer and increasing the transfer effect across membranes.
