微环境对“D-π-A”型荧光分子发光行为的影响

本文通过研究自制的6种“D-π-A”型共轭有机盐类染料在不同环境中的发光行为,讨论了环境和分子结构对其发光行为的影响。研究结果表明:(1)巴比妥酸盐类可看出引入羟基发生较明显的荧光淬灭现象,且发光峰位显著蓝移;(2)通过比较喹啉盐类吡啶盐类荧光光谱,可知吡啶基受体具有良好的发光特性;(3)三类有机盐的荧光强度均随着溶剂极性的增大而减小,且有不同程度的蓝移。

Environment To Fluorescent Molecules In Radiant Actions

Those fluorescent molecules which have “D-π-A” conjugated systems present well radiant action and non-linear optical identity. Because of intensively interfere by the radicals in compound, the molecules are sorely polarized. Besides, it will bring the huge distinction between the ground state and the excitated state. Thus, the same fluorescent stuff has distinct spectral figure and intensity. This article studies the effect of solvent on radiant action from three kind of organic dyes in four different solvents.
