An aggregation-induced emission enhancement (AIEE)-active fluorescent sensor has been successfully designed and synthesized, combining the AIE effect of tetraphenylethylene (TPE) with the cyanide acceptor of phenanthro[9,10-d]imidazole. The sensor exhibits not only the property of AIEE in DCM/n-hexane or THF/H₂O, but also the phenomenon of mechanofluorochromic (MFC). It displays large Stokes shift (107 nm) due to the intramolecular charge transfer (ICT) process. The cation of CN⁻ boosts the ICT process to make the greater Stokes shift (184 nm) with the fluorescent color vary from blue-green to sodium-yellow and visually turning from light yellow to dark yellow in the naked eyes. The results of Job's plot, ESI-MS and the DFT calculations provide the stoichiometric ratio and electronic properties of the sensor. Furthermore, the sensor could be applied to qualitative and quantitative detection of CN⁻ on test paper strips.

结合四苯基乙烯（TPE）的AIE效应和菲咯[9,10- d ]咪唑的氰化物受体，成功设计并合成了一种聚集诱导发射增强（AIEE）活性荧光传感器。该传感器表现出不仅在DCM / AIEE的属性ñ己烷或THF / H ₂ O，而且mechanofluorochromic（MFC）的现象。由于分子内电荷转移（ICT）过程，它显示出较大的斯托克斯位移（107 nm）。CN的阳离子^-增强ICT过程，使斯托克斯位移（184 nm）更大，荧光颜色从蓝绿色变为钠黄色，肉眼从浅黄色变为深黄色。乔布图，ESI-MS和DFT计算的结果提供了传感器的化学计量比和电子特性。此外，传感器可以被应用到CN的定性和定量检测^-对试纸条。
