Preparation and Spectral Properties of Two Fluorescent LB Films

Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022

Received Date: 1 July 1994
Revised Date: 27 December 1994

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 luminescence properties of these molecules in films have been investigated by absorption and fluorcscence spectroscopy. The content of cis-form DCM in LB film was found to be greatly increascd in comparison with that in solution.
- fluorescent LB film,
- dicyanomethylene-methyl-p-dimethylaminostyryl-4H-py-ran,
- bis(methylbenzoxazolyl)ethylene
