摘要
通过Sonogashira偶合反应合成了3种含pentiptycene基团、侧链分别含对称烷氧基取代、含非对称烷氧基取代和含烷基取代的聚对苯撑乙炔衍生物PPE-A、B和C。采用1 H NMR,FT-IR,UV-Vis和PL等仪器对其进行了表征。讨论了侧链取代基类型对PPE溶解性和光学性能的影响;研究了间二硝基苯(m-DNB)和对硝基甲苯(p-NT)两种硝基化合物对PPE-A和B溶液的荧光淬灭影响,结果表明,PPE-A和B具有很高的荧光强度,对m-DNB和p-NT显示出良好的荧光响应。
Three poly（p-phenyleneethynylene, PPE） derivatives containing pentiptycene group were synthesized through sonogashira coupling reaction. They were PPE-A with symmetrical substitutes, PPE-B with symmetrical alkoxyl substitutes and PPE-C with alkyl substitutes. PPEs were characterized by 1H NMR and FT-IR, UV-Vis and PL. The influence of different benzene ring side chain on the solubility and spectrum of PPEs were studied. The fluorescence quenching properties of PPE-A and B versus two nitro-aromatic compounds were also studied. The results showed that they have a good fluorescence response to m-DNB and p-NT.
