摘　　要：利用配位反应,以稀土Sm^(3+)为中心发光离子,丙烯酰胺,月桂醇,8-羟基喹啉合成的CAHD单体为主要配体,phen为协同配体,与甲基丙烯酸甲酯共聚,合成了一种键合型含钐稀土有机大分子配合物转光剂(Sm(CAHD)_2phen-co-MMA).采用元素分析、IR、XPS、UV、荧光光谱、XRD、TGA等测试手段对Sm(CAHD)_2phen-co-MMA的结构、光学性能及热稳定性进行研究.结果表明,在315 nm的紫外光激发下,Sm(CAHD)_2Phen-co-MMA在560 nm、620 nm和650 nm均出现了Sm^(3+)的特征发射峰,在650 nm处强度最大,与植物进行光合作用光谱的吻合性较高.转光剂降解温度在182℃,具有良好的热稳定性.所合成转光剂具有优良的光学性能,在高温下不易被降解,有望作为农膜转光剂使用.A novel samarium-containing rare-earth organic macromolecular complex transmutation(Sm(CAHD)2phen-co-MMA)was synthesized using a coordination reaction with rare-earth Sm 3+as the central luminescent ion,acrylamide,lauryl alcohol,and 8-hydroxyquinoline synthesized as the main ligand and phen as the co-ligand,and copolymerized with methyl methacrylate.The structure,optical properties,and thermal stability of Sm(CAHD)2phen-co-MMA were investigated by Elemental analysis IR,XPS,UV,fluorescence spectroscopy,XRD,TGA,and other testing methods.The results showed that the characteristic emission peaks of Sm 3+appeared at 560 nm,620 nm,and 650 nm for Sm(CAHD)2phen-co-MMA under UV excitation at 315 nm,with the highest intensity at 650 nm and a good match with the photosynthesis spectrum performed by plants.The degradation temperature of the light conversion agents was 182℃,which has good thermal stability.The synthesized light conversion agents has excellent optical properties and is not easily degraded at high temperatures,so it is expected to be used as a light conversion agent for agricultural films.
