四苯乙烯（TPE），一个典型的发光团与聚集诱导发射（AIE），接枝到盐响应肽，以产生一个发光的水凝胶因子。在测试了不同的参数后，我们发现只有在盐的存在下，而不是在温度、pH和溶剂的存在下，单分散水凝胶因子才能自组装成具有明亮发光的水凝胶网络，诱导发光是动态变化的，并且能够真实的实时监测水凝胶的形成。将AIE分子光栅化到刺激响应肽上是一种很有前途的方法，用于开发用于生物应用的自显示软材料。
Tetraphenylethylene (TPE), an archetypal luminogen with aggregation-induced emission (AIE), was grafted to a salt-responsive peptide to yield a yet luminescent hydrogelator. After testing different parameters, we found that only in the presence of salt rather than temperature, pH, and solvent, did the monodisperse hydrogelators self-assemble into a hydrogel network with bright emission turned on. The induced luminescence was a dynamic change and enabled real time monitoring of hydrogel formation. Grating AIE molecules to stimuli-responsive peptides is a promising approach for the development of self-revealing soft materials for biological applications.
