【摘要】 通过8-羟基喹啉的氯甲基化,预先合成5-氯甲基-8-羟基喹啉,在催化剂无水醋酸钠的作用下,再使之与双官能团的化合物氯乙醇反应,合成具有反应活性点的8-羟基喹啉的衍生物(C lCH2CH2OCH2-Hq),然后与含有A l3+,Zn2+,L i+的金属化合物及8-羟基喹啉经由配位反应,合成了可溶性的具有单反应活性点的小分子8-羟基喹啉金属配合物(这些配合物含有A lQ3,ZnQ2,L iQ基团),这类化合物可以接枝到高聚物上,得到高相对分子质量的含8-羟基喹啉金属配合物的发光材料1。HNMR、FTIR、元素分析确定了小分子8-羟基喹啉金属配合物的组成;紫外吸收光谱(UV)、光致发光光谱(PL)说明小分子8-羟基喹啉金属配合物的发光来自于A lQ3,ZnQ2,L iQ基团。更多还原

【Abstract】 A kind of novel luminescent materials,small molecular 8-hydroxyquinoline metal（Al,Zn,Li） complexes with single reactive group were synthesized.Functional 8-hydroxyquinoline（5-chloromethyl-8-quinolinol hydrochloride） was firstly obtained by chloromethylation of 8-hydroxyquinoline.Then its derivative with single reactive group —CH₂OCH₂CH₂Cl was synthesized by reaction with bifunctional reactant chlorohydrin using anhydrous sodium acetate as catalyst.Metaloquinolate-containing complexes were finally prepared by coordination reaction of the derivative with metal ions and 8-hydroxyquinoline.These complexes can be grafted to polymers via the reactive group.It may be a new path to synthesize luminescent materials containing 8-hydroxyquinoline metal complexes.Structures of the intermediates and metal complexes were characterized by ¹HNMR,FTIR and elementary analysis.UV-vis absorption and PL emission spectra proved that the luminescent center came mostly from the AlQ₃,ZnQ₂,LiQ units.更多还原
