采用“点击”化学方法设计合成了一种新型的含三氮唑和苯环的单体2-(1-naphthalen-1-ylmethyl-1H-[1，2，3]triazol-4-yl)-ethyl甲基丙烯酸酯(NTEMA)。以2-氰基丙基-2-二硫代苯甲酸酯(CPDB)为RAFT试剂，2，2‘-偶氮二异丁腈(AIBN)为引发剂，在四氢呋喃(THF)溶液中成功地进行了Ntema的RAFT聚合。结果表明，聚合反应具有“活性”/可控特性。将合成的poly(2-(1-naphthalen-1-ylmethyl-1H-[1，2，3]triazol-4-yl)-ethyl(甲基丙烯酸甲酯)均聚物PNTEMA进一步与钐离子配位，制备了含稀土的聚合物(PNTEMA-Sm(III)配合物)，并用红外光谱、差示扫描量热法和电感耦合等离子体发射光谱对其进行了表征。表征数据证实了聚合物侧链上的三氮唑能够与Sm(III)配位。研究了聚合物及其聚合物Sm(Ill)络合物在溶液和膜中的荧光性质。(C)2008爱思唯尔有限公司。保留所有权利。
A novel monomer containing triazole and naphthalene ring, 2-(1-naphthalen-1-ylmethyl-1H-[1,2,3]triazol-4-yl)-ethyl methacrylate (NTEMA), was designed and synthesized via "click" chemistry method. The RAFT polymerization of NTEMA was successfully carried out using 2-cyanoprop-2-yl dithiobenzoate (CPDB) as a RAFT agent, 2,2'-azobisisobutyronitrile (AIBN) as an initiator in tetrahydrofuran (THF) solution. The results showed that the polymerizations exhibited "living"/controlled characteristics. The obtained poly(2-(1-naphthalen-1-ylmethyl-1H-[1,2,3]triazol-4-yl)-ethyl methacrylate) homopolymers, PNTEMAs, were further coordinated with samarium ion to prepare rare earth containing polymers (PNTEMA-Sm(III) complexes) which were characterized by FT-IR, DSC and ICP-AES. The characterization data confirmed that triazole in side chain of the polymer could coordinate with Sm(III). The fluorescence property of the polymers and polymer Sm(Ill) complexes were investigated in solution and in film. (C) 2008 Elsevier Ltd. All rights reserved.
