emissions is more essential. Here we report a pillar[6]arene and tetraphenylethene (TPE)-based supra-amphiphile, which shows dual-responsiveness and tunable emission intensity. By introducing azobenzene units to a TPE fluorophore, the fluorescence is quenched via photo-induced electron transfer, whereas the emission regains upon the complexation with pillar[6]arene.

随着对智能荧光材料需求的增长,开发具有可控排放的新系统变得更加重要。在这里,我们报告了一种基于支柱[6]
芳烃和四
苯乙烯(TPE)的超两亲物,它显示出双重反应性和可调的发射强度。通过将
偶氮苯单元引入TPE荧光团,荧光通过光诱导的电子转移而猝灭,而发光在与柱[6]
芳烃络合后重新获得。受益于
偶氮苯的光和还原反应性,超两亲物的荧光强度可以容易地控制。在外部刺激下也发现包括纳米颗粒和纳米带的自组装形态。这项工作显示了一种构造智能荧光材料的新方法。
