Multicolor mechanochromic luminescent (MCL) materials are promising candidates in fundamental science and practical applications. In this paper, a series of novel smart luminescent compounds based on a cyanostyrene unit, NAIF, NA-15C5, NAPM, NAIP and NAPF, have been developed. NAIF, NAPM, NAPF and NAIP all exhibit aggregation-induced emission (AIE) characteristics and individually show red, orange
多色机械致变色发光(MCL)材料在基础科学和实际应用中是很有前途的候选材料。本文开发了一系列基于氰基苯乙烯单元NAIF,NA-15C5,NAPM,NAIP和NAPF的新型智能发光化合物。NAIF,NAPM,NAPF和NAIP均显示聚集诱导发射(AIE)特性,并且在聚集状态下分别显示红色,橙色,黄色和绿色发射。发光剂NA-15C5和NAPM具有可逆的三色变化MCL行为。全国工业联合会NAIP和NAIP显示出双色切换的机械变色现象。另外,两种晶体多晶型物NAPM- y和NAPM- o具有明亮的黄色和橙色发光颜色的不同分子堆积模式,合理地解释了三色变化的机械变色机理。而且,发光剂NAIP可以用作无墨可重写纸。
