以邻羟基苯甲醛、邻氨基巯酚、丙二腈为原料合成了有机光致发光材料6-氯甲基-3-(2-苯并噻唑基)-香豆素,将这种新型香豆素与甲基丙烯酸甲酯(MMA)、甲基丙烯酸二甲胺基乙酯(DM)的共聚物(CPA)进行季铵化反应,制得侧基上带有不同配比香豆素的新型发光高分子化舍物(C—CPA)。通过差示扫描量热法(DSC)、凝胶色谱法(GPC)、FT—IR和UV—Vis证明了接枝反应是成功的。同时研究发现接技香豆素的高分子化合物具有很好的荧光性能,这为合成具有优异发光性能的接技型高分子功能材料提供了一条新的途径。
An organic photoluminescent compound 3-(2-benzothiazolyl)-6- chloromethyl- Coumarin was synthesized by using 2-hydroxybenzaldehyde, 2-aminothiophenol and malononitrile. Let this novel coumarin take quaternary ammonium reactions with the copolymer of methyl methacrylate-2- (dimethylamino) ethyl mcthacrylate, and then some special coumarin side-chain polymers (C-CPA) could be obtained. The results of DSC, GPC, FT-IR and UV-Vis for C-CPA prove that the graft reactions are successful, and further studies on C-CPA show that the novel polymers have excellent fluorescence properties. Thus, side-chaln graft reactions may provide a new way for the synthesis of polymer functional materials with excellent luminescence properties.
