摘要

从理论上研究了萘醌衍生物和噻唑衍生物分子之间的相互作用

并通过光谱实验进行了验证.研究结果表明:萘醌衍生物和噻唑衍生物均为多环有机共轭分子

且分子结构呈平面构型.在固态时呈多晶粉末状

有着强烈的光吸收

但无可见光发射.可是

将其分散于聚乙烯树脂中

其呈单分子形态

能产生可见光.通过比较萘醌衍生物和噻唑衍生物的荧光光谱和激发光谱

发现萘醌衍生物的荧光光谱与噻唑衍生物的激发光谱有很好的重叠.这样

将萘醌衍生物和噻唑衍生物均匀混合分散到聚乙烯树脂中

用蓝光激发萘醌衍生物就可观察到噻唑衍生物发射的红光.这说明二者之间产生了能量传递

实现了蓝光激发下产生的红光.实验还发现

采用适当比例的配制可得到能量传递效率最高的混合膜.这对于光转换白光LED的研发工作是非常有意义的.

Abstract

Molecule interaction between naphthaquinones and thiazole was studied with F

-rster theory and experimental investigation.It was found that the excitation spectrum taken from the thiazole derivative polythene resin film has a peak around 602 nm with a width of 30 nm

which overlaps the emission band of naphthaquinones derivative polythene resin film.This suggests that energy transfer can occur between thiazole and naphthaquinones molecules.So new luminescence materials could be made by changing the chromophore into the fluorophores.This work is very significant for the development of the white LED by light conversion.
