制取了４－二氰基亚甲基－２－甲基－６－对二甲胺基苯乙烯基－４Ｈ－吡喃（ＤＣＭ）和１，２－双（５－甲基苯并唑）基乙烯（ＤＴ）两种荧光分子的ＬＢ膜以及两者的混合膜。以吸收光谱和荧光光谱探讨了膜中分子的构型、微环境、发光性能等特征。发现在ＬＢ膜的缀密排布环境中ＤＣＭ顺式构型的含量较之在溶液中大为增加。
Preparation of 4-dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4H-pyran (DCM) and 1,2-bis (5-methylbenzoxazole) LB film with two kinds of fluorescent molecules of vinyl ethylene (DT) and a mixed film of the two. The characteristics of the molecular configuration, microenvironment and luminescent properties of the film were discussed by absorption spectra and fluorescence spectra. It was found that the content of cis-configuration of DCM in the dense arrangement of LB film was greatly increased compared with that in solution.
