利用荧光光谱、紫外可见吸收光谱研究了方块菁染料在不同极性的溶剂中的光谱性质的变化,并利用LB膜技术、Brewster角显微镜及荧光光谱、紫外可见吸收光谱研究了不同极性的铺展溶剂对染料的铺展形态及制备的LB膜样品的光谱性能的影响,说明了分子组装在形成功能薄膜中的重要性.
Fluorescence spectra and UV-vis absorption spectra were used to study the spectral properties of the cyanine dyes in solvents with different polarities. LB films, Brewster’s angle microscope, fluorescence spectra and UV-Vis absorption spectra were used to investigate the effects of different polarity The influence of the solvent on the spreading morphology of the dye and the spectral properties of the prepared LB film sample illustrates the importance of molecular assembly in forming the functional film.
