摘　　要：报道了一种基于咔唑吡啶功能化的α-氰基二苯乙烯衍生物(CZ-CNPY/12)可发生光致发光的酸致变色现象。其中α-氰基二苯乙烯单元赋予了CZ-CNPY/12聚集诱导发光性质。由于其骨架中含有苯基吡啶,该激活发光的光电性质也可以通过质子化进行调控。加入三氟乙酸(TFA)后,在溶液中的光致发光增强了6倍,发射波长红移了110 nm。利用CZ-CNPY/12的薄膜在酸碱刺激下可逆的光学特性,制备了防伪纸。此外,酸致变色实现了多色光绘图案。In this paper,a carbazole pyridine-functionalizedα-cyanostilbene derivative(CZ-CNPY/12)was reported,which can undergo photoluminescence acid-induced discoloration.Theα-cyanostilbene unit endows CZ-CNPY/12 with aggregation-induced luminescence properties.Since its skeleton contains phenylpyridine,the photoelectric properties of the activated luminescence can also be regulated by protonation.After the addition of trifluoroacetic acid(TFA),the photoluminescence in the solution was enhanced by 6 times,and the emission wavelength was red-shifted by 110 nm.Anti-counterfeiting paper was prepared by using the reversible optical properties of CZ-CNPY/12 films under acid-base stimulation.In addition,acid discoloration achieves multi-color light painting patterns.
