手性联萘酚高分子由单体(R)-3,3′-二炔基-6,6′-二正丁基-2,2′-联萘酚(R-M-1)和对苯二叠氮(M-1)通过CuAAC反应得到,通过1HNMR、13CNMR、FTIR、旋光度、GPC、热分析、荧光光谱等方法对单体和高分子进行了结构表征和性能测试。该高分子是通过“Click”反应得到的手性联萘酚高分子,本文探讨了手性高分子传感器对各种金属离子的荧光传感性质,结果表明,与其他离子如K+、Mg2+、Pb2+、Co2+、Ni2+、Ag+、Cd2+、Cu2+、Zn2+等相比,Hg2+几乎使高分子荧光完全淬灭。这表明,以三氮唑基团作为连接基团和识别位点的高分子可作为有效识别Hg2+的荧光化学传感器。
The chiral binaphthol polymer consists of monomer (R) -3,3’-diynyl-6,6’-di-n-butyl-2,2’-binaphthol (RM- Azide (M-1) was obtained by CuAAC reaction. The structures and properties of monomers and polymers were characterized by 1HNMR, 13CNMR, FTIR, optical rotation, GPC, thermal analysis and fluorescence spectroscopy. The polymer is a chiral binaphthol polymer obtained by the “Click ” reaction. The fluorescence sensing properties of the chiral polymer sensors for various metal ions are discussed in this paper. The results show that with the other ions such as K +, Mg2 + , Pb2 +, Co2 +, Ni2 +, Ag +, Cd2 +, Cu2 +, Zn2 +, etc., Hg2 + almost completely quenches the fluorescence of the polymer. This shows that the triazole group as a linker and a recognition site of the polymer can be used as a fluorescent chemical sensor to effectively identify Hg2 +.
