稀土与2-羰基丙酸水杨酰腙及1,10-菲啰啉配合物的合成及其光学性质

Synthesis and Optical Properties of Re(Ⅲ) Coordination Cmplexes Constructed by Alicylaldehyde Salicylhydrazone and 1,10-Phenanthroline

合成了12个新型的稀土(RE)与2-羰基丙酸水杨酰腙(H3L)和1,10-菲啰啉(phen)的三元配合物[RE2(H2L)2(HL)2·(phen)·n H2O(RE=La,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Er,Yb,Lu和Y)(1La^1Y)],其结构经1H NMR,IR和元素分析表征。利用UV-Vis和FL研究了1La^1Y的光学性质。结果表明,1La^1Y的λmax均位于322 nm^326 nm和297 nm^301 nm。

Twelve novel ternary complexes[RE2（ H2L）2（ HL）2·（ phen） ·n H2O（ RE = La,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Er,Yb,Lu and Y）（ 1^La- 1^Y） ]were synthesized by coordination reaction of salicylaldehyde salicylhydrazone（ H3L）,1,10-phenanthroline（ phen） and rare earth（ RE）.The structures were characterized by1 H NMR,IR and elemental analysis. The optical properties of1^La- 1^Ywere investigated by UV-Vis and FL. The results indicate that λmaxof 1^La- 1^Ywere 322 nm -326 nm and 297 nm - 301 nm.
