具有光致变色和发光性能的有机化合物的合成及其性能研究

Synthesis and Characteristics of Compounds Having Both Photochromic and Fluorescent Character

以吲哚啉螺苯并吡喃与香豆素衍生物为原料 ,用 DCC缩合酯化法在温和条件下合成了 8种新的具有光致变色和发光性能的化合物 ,确定了结构 ,研究了紫外光谱、荧光光谱及光致变色性 .所得化合物同时具有光致变色和发荧光的双重特性 ,而且荧光光谱中有两个激发波长 ,每一个波长对应产生一个不同的荧光发射峰 .

Eight new compounds which have both photochromic and fluorescent character have been synthesized by esterification reaction in the presence of DCC from the derivatives of indolinospirobenzopyrans and coumarins. The structure of these new compounds were identified and their spectrum properties were studied. The new compounds were shown to be have both photochromism character and fluorecent character, and their fluorescent spectrum have two exciting wavelength and two different emitting peak respectively. They were expected to be applied in such areas as anti forgery materials, bio labeling reagents, and other multiple functional materials. [WT5HZ]
