利用ＬＢ技术制备螺吡喃有序分子膜，研究了气液界面上螺吡喃材料在不同成份和不同ｐＨ值亚相时的成膜行为，着重研究了螺吡喃在ＬＢ膜这个特殊介质环境中不同于溶液的光致变色机理和光学性质
The LB film was used to prepare the spiropyran molecular film. The film formation behavior of spiropyran at gas-liquid interface with different compositions and different pH subphases was studied. The effect of spiropyran on LB film was studied Is different from the photochromic mechanism and optical properties of the solution
