摘    要:通过含乙烯键的三联吡啶单体与甲基丙烯甲酯单体的共聚,制备了含配体的线性共聚物(P(MMA-co-TPY))。该共聚物继续与环金属铱二氯桥中间体反应,最终制备出含环金属铱配合物的高分子材料P(MMA-co-TPYIr)。用傅里叶变换红外光谱(FTIR)表征了材料的结构,并用紫外-可见光谱仪、荧光光谱仪研究了材料的光物理性能,最后研究了材料在溶液中的氧气传感性能。结果表明,环金属铱配合物已共价连接到高分子链上,固态下为纯红光发射,波长为638 nm,量子效率为0.035。该材料表现出了较好的氧气传感性能,并且在DMF中的效果最好,纯氮气和纯氧气氛围下的发光强度比为6,氧气检测限能达到0.34%。

关 键 词:环金属铱配合物  聚甲基丙烯酸甲酯  三联吡啶  氧分子传感

Abstract:A linear copolymer (P(MMA-co-TPY)) containing ligands was prepared by the copolymerizing terpyridine monomer and methyl methyl acrylic monomer. Then the copolymer reacted with IrⅢ-chloro-bridged intermediate reaction, a polymeric material (P(MMA-co-TPYIr)) containing cyclometalated iridium complex was eventually obtained. Ring metal iridium complexes containing polymer P(MMA-co-TPYIr). The material was characterized by Fourier transform infrared spectra (FTIR), its optical properties and oxygen sensor performance were studied by ultraviolet-visible spectrometer, fluorescence spectrometer. The results show that the cyclometalated iridium complex groups have been covalently connected to the polymer chain, the luminescence wavelength is 638 nm in solid state which belonging to pure red light emission, and the quantum efficiency of 0.035. The material shows good oxygen sensor performance especially in DMF, the luminous intensity ratio is 6 in pure nitrogen and pure oxygen atmosphere. Its oxygen detection limit could reach 0.34%.
Keywords:cyclometalated iridium complex  polymethylmethacrylate  terpyridine  oxygen sensor
