设计并合成了两种新型二芳基大环冠醚共轭8-羟基喹啉衍生物7a和7b及其锌配合物, 通过核磁共振(1H NMR, 13C NMR)、质谱(MS)、红外光谱(FT-IR)和紫外光谱(UV)等对7a和7b进行了结构表征. 初步研究了7a和7b及其锌配合物在溶液中的光致发光性质. 结果表明, 相对于2-甲基-8-羟基喹啉, 化合物7a和7b的荧光光谱向长波方向有明显的移动, 分别在460和467 nm处出现发射峰, 处于蓝光的范围. 配合物8a和8b的荧光发射峰分别为562和665 nm, 属黄光范围, 但荧光强度较弱.

Two novel bisphenylene crown ether conjugated quinolin-8-ol derivatives (7a, 7b) and their zinc complexes were designed and synthesized. The structures of 7a and 7b were identified by UV-Vis, 1H NMR, 13C NMR, IR and MS techniques. The photofluorescence properties of 7a, 7b and their zinc complexes in solution were also studied. Their luminescent properties indicate that the emission wavelengths of 7a and 7b are at 460 and 467 nm, having a significant red shift compared to 2-methyl-8-hydroxyquinoline. The zinc complexes have weak light-emission at 562 and 565 nm respectively.
