Traditional fluorescent molecules are easily quenched in most solid applications. Materials with aggregation‐induced emission (AIE) characteristics offer a new way to solve this problem. In this paper, polymer composites consisting of tetraphenylethene (TPE) with AIE properties and polydimethylsiloxane (PDMS) are developed by a simple blending method. The prepared material shows a variable fluorescent emission with different TPE concentrations in the polymer matrix. Such a unique phenomenon arises mainly from the transition of the AIEgen from the crystal to the amorphous state. Interestingly, the fluorescent emission of composites is strongly affected by external factors, such as temperature and mechanical conditions, thus giving the material a stimuli‐sensitive fluorescence property. Specifically, the fluorescence intensity of composites decreases with an increasing temperature, and the same response exhibits when the mechanical force is applied to the material. The excellent response of composites to the temperature and mechanical deformation guarantees the sensory applications of the developed material.

具有AIEgens的复合材料用于温度传感和应变测量

传统的荧光分子在大多数固体应用中很容易被淬灭。具有聚集诱发发射（AIE）特性的材料提供了解决此问题的新方法。在本文中，通过简单的共混方法开发了由具有AIE特性的四苯乙烯（TPE）和聚二甲基硅氧烷（PDMS）组成的聚合物复合材料。制备的材料在聚合物基质中显示出不同的TPE浓度的可变荧光发射。这种独特的现象主要是由于AIEgen从晶体到非晶态的转变而引起的。有趣的是，复合材料的荧光发射受到外部因素的强烈影响，例如温度和机械条件，因此赋予了材料刺激性的荧光特性。特别，复合材料的荧光强度随着温度的升高而降低，而当机械力施加到材料上时，会表现出相同的响应。复合材料对温度和机械变形的出色响应保证了开发材料的感官应用。
