摘要
合成双分子膜的功能化是近年来引人注目的研究课题之一,它为以可控制方式合成开发功能材料和仿生器件提供了一条趋于实际意义的途径。
Single chain amphiphiles containing Schiff base chromophore can organize intobilayer membrane as vesicles in aqueous solution. The fluorescence excitation andemission intensities of Schiff base group are markdly influenced by the phase states ofthe bilayer membrane.At T<30℃, fluorescence intensities decrease slightly, but dras-tically between 30--40℃ and between 45--55℃,just corresponding to the phase tran-sition temperatures 37℃ and 46℃ respectively, given by DSC. So the tight arrange-ment in molecules greatly enhances the lumination efficiency. According to the agg-regate states, the fluorescence emission intensity follows the series as: I(gel state)>I(liquid state)>I(molecular dispersion state).
