摘要: 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-甲基苯并噁唑)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.

Abstract: The LB films of two fluorescent molectiles,4-dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4H-pyran(DCM)and 1,2-bis(5-methylbenzoxazol-2-yl)ethylene(DT)and their mixture were prepared. The configtiration, micro environment and luminescenceproperties of these molecules in films have been investigated by absorption and fluorcscencespectroscopy, The content of cis-form DCM in LB film was found to be greatly increascd incomparison with that in solution.

Key words: fluorescent LB film, dicyanomethylene-methyl-p-dimethylaminostyryl-4H-py-ran, bis(methylbenzoxazolyl)ethylene
