【摘要】 本文合成了一种以二苯乙烯为骨架的固体荧光染料，并对其进行了基础的光物理性质研究。实验结果显示，在DMSO溶液中，该染料的最大紫外吸收峰为395 nm,最大荧光发射峰为560 nm;固体最大荧光发射峰为547 nm,荧光为黄绿色；该染料具有明显的溶致变色效应，随着溶剂极性的增大，溶液的最大发射波长出现显著红移，呈现了从蓝色到黄色的大跨度变色。更多还原

【Abstract】 A solid fluorescent dye based on a stilbene backbone was synthesized and its basic photophysical properties were investigated.The experimental results showed that the maximum UV absorption peak of the dye was 395 nm and the maximum fluorescence emission peak was 560 nm in DMSO solution.The solid maximum fluorescence emission peak was 547 nm, and the fluorescence was yellowish green.The dye has an obvious solvatochromic effect, with the increase of solvent polarity, the maximum emission wavelength of the solution showed a significant red shift, showing a large span of color change from blue to yellow.更多还原
