通过三氯化铕、邻菲啰啉(phen)、噻吩基三氟1,3丁二酮(TTA)及丙烯酸(AA)制得铕配位单体(ECM),再与甲基丙烯酸甲酯(MMA)聚合成侧链连有铕配位发光单元的聚合物(ECM与MMA的摩尔比1∶60和1∶30)。红外光谱、核磁共振谱等确认其结构。铕配位单体的最大吸收波长为341nm,最大发射波长为613nm。聚合物的荧光光谱由两个区域组成:350~500nm和602~630nm,最大发射波长为613nm,这是由铕离子的f-f*跃迁引起。Eu3+的发光来自单体(ECM)中各配位体的能量传递以及丙烯酸与甲基丙烯酸甲酯聚合后高分子链的F rster能量转移。该类聚合物有良好的发光性、溶解性和分散性。
通過三氯化銪、鄰菲啰啉(phen)、噻吩基三氟1,3丁二酮(TTA)及丙烯痠(AA)製得銪配位單體(ECM),再與甲基丙烯痠甲酯(MMA)聚閤成側鏈連有銪配位髮光單元的聚閤物(ECM與MMA的摩爾比1∶60和1∶30)。紅外光譜、覈磁共振譜等確認其結構。銪配位單體的最大吸收波長為341nm,最大髮射波長為613nm。聚閤物的熒光光譜由兩箇區域組成:350~500nm和602~630nm,最大髮射波長為613nm,這是由銪離子的f-f*躍遷引起。Eu3+的髮光來自單體(ECM)中各配位體的能量傳遞以及丙烯痠與甲基丙烯痠甲酯聚閤後高分子鏈的F rster能量轉移。該類聚閤物有良好的髮光性、溶解性和分散性。

Europium complexed monomer (ECM) was prepared by a mixture of EuCL3, thenoyltrifuoroacetone (TTA), acrylic acid (AA) and 1, 10-phenanthroline (phen) and then two copolymers of poly(methyl methacrylate (MMA)-eo-ECM) (molar ratio for ECM/MMA, 1/60 and 1/30), which grafted with Europium complex as lightemiting unit, were synthesized. The structures were characterized by FT-IR, 1HNMR. The maximum absorption and emission wavelength of ECM were at 341nm and 613nm respectively. The emission spectra of the copolymers consisted of two emission bands, one between 350- 500nm and the other centered at 613nm between 602-630nm, corresponding to f-f transitions of europium ions. Emission of Europium ions not only originated from energy transfer of ligands in ECM but also from Forster energy transfer of the main chain of polymers. This kinds of polymers exhibited desirable luminescence, solubility and dispersion.
