a wide variety of applications such as sensors, memory devices, motion systems, security systems, and so forth. However, only few design principles have been disclosed, which greatly impedes the growth of mechanofluorochromic dyes. Here, a strategy of molecular design for mechanochromic luminescence is reported, based on the cation–anion interaction‐directed switching of molecular stacking. On the basis
机械氟致变色材料在诸如传感器,存储设备,运动系统,安全系统等广泛的应用中具有巨大的潜力。然而,仅公开了很少的设计原理,这极大地阻碍了机械氟致变色染料的生长。在此,报告了基于阳离子-阴离子相互作用指导的分子堆叠转换的机械变色发光分子设计策略。在此策略的基础上,设计了一系列常见的N-杂芳族鎓荧光团,如咪唑鎓,1,2,4-三唑鎓,三唑并吡啶鎓,苯并咪唑鎓,γ-咔啉鎓和吡啶鎓盐,并被证明具有惊人的可逆机械荧光变色行为。 。
