设计合成了3种新型含单氟8-羟基喹啉衍生物配体:(E)-2-[2-(2-氟代苯基)乙烯基]-8-羟基喹啉(4a)、(E)-2-[2-(3-氟代苯基)乙烯基]-8-羟基喹啉(4b)、(E)-2-[2-(4-氟代苯基)乙烯基]-8-羟基喹啉(4c)及其相应的锌配合物(5a)、(5b)、(5c),利用1 H-NMR、IR、MS、元素分析确认了其结构。测定了它们在DMF溶液中的荧光性质;荧光光谱显示化合物4a、4b、4c在DMF溶液中的λmax分别是505nm、487nm、513nm;5a、5b、5c的λmax分别是559nm、598nm、588nm,荧光光谱显示氟基位置的改变可以调控8-羟基喹啉锌配合物的发光性质。
Three novel monofluoro 8-hydroxyquinoline derivatives ligands were designed and synthesized: (E) -2- [2- (2- fluorophenyl) ethenyl] E) -2- [2- (3-fluorophenyl) vinyl] -8-hydroxyquinoline (4b) The structures of 8-hydroxyquinoline (4c) and its corresponding zinc complexes (5a), (5b) and (5c) were confirmed by1H-NMR, IR, MS and elemental analysis. The fluorescence spectra of compounds 4a, 4b and 4c in DMF solution were 505nm, 487nm and 513nm respectively. The λmax of 5a, 5b and 5c were 559nm, 598nm and 588nm, respectively. The fluorescence The spectra show that the change of the position of fluorine can regulate the luminescent properties of 8-hydroxyquinoline zinc complex.
