摘　　要：冠醚和二级铵盐结构的分子经常被用来构建超分子自组装体,报道了一种不对称的四苯乙烯衍生物单体,其分别与二苯并-24-冠-8(DB24C8)和二级铵盐结构单元通过点击化学反应连接,通过核磁共振氢谱、碳谱和质谱得到结构表征.通过核磁滴定显示出冠醚和二级铵盐结构在酸性条件下能够形成超分子组装体,并初步研究了其在乙腈/水溶液中的聚集诱导荧光性能.Dibenzo-24-crown-8（DB24C8） and dibenzylammonium（DBA） are always utilized for the construction of supramolecular assemblies. We reported a new kind supramolecular assembly polymer constructed by M1 which was synthesized from tetraphenylethene（TPE） linked with DB24C8 and DBA through click reaction. The chemical structures of all the compounds were fully characterized by ~1H NMR, ^（13）C NMR, and MS. The ~1H NMR titration showed that the supramolecular assembly was successfully constructed in acidic condition. The fluorescent results showed that the assemblies displayed ratio-metric properties with the changes of aggregation-induced emission and monomer-emission, and fluorescence quenching with addition of Pd2＋.
