摘要

力致变色荧光材料具有机械力刺激响应的性能，在压敏传感等领域有着广阔的应用前景。本文制备了一种具有聚集诱导发光效应的二氰基二苯乙烯基苯衍生物(DCS-Bn)，采用高分辨质谱对其化学结构进行了表征。通过吸收光谱和荧光发射光谱研究了DCS-Bn的光物理性质，并使用差示扫描量热仪和X射线粉末衍射仪考察了其聚集态结构。实验结果表明，DCS-Bn在溶液和固体状态均具有较强的发光性能。并且，基于DCS-Bn独特的棒状分子结构及“晶态-非晶态”的聚集态结构变化，该材料具有力致发光变色性质。采用溶剂熏蒸或者加热处理，DCS-Bn荧光颜色又能恢复，在可重复书写荧光材料等领域具有潜在应用价值。

Abstract

Mechanochromic luminescent materials have potential applications in pressure sensitive sensing due to their mechanical response properties. In this paper

a dicyanodistyrylbenzene(DCS) derivative(DCS-Bn) with aggregation-induced emission(AIE) property was synthesized

and its molecular structure was characterized by high-resolution mass spectra. The photophysical properties of DCS-Bn were studied by absorption spectra and fluorescence emission spectra. Furthermore

the aggregation structures of DCS-Bn were measured by differential scanning calorimetry and X-ray diffraction experiment. The results revealed that DCS-Bn has high efficiency luminescence both in solution and solid state. DCS-Bn has the mechanofluorochromic property due to its unique rod molecular structure and the changes of aggregated structures(crystalline or amorphous state). The fluorescence emission color can recover to pristine state through solvent fuming or heating treatment

thus

DCS-Bn has potential application value in the fields of rewritable fluorescent materials.
