A new 4,5-diazafluorene-based fluorescent chemosensor has been synthesized by Schiff base condensation of 9,9-bis(3,5-dimethyl-4-aminophenyl)-4,5-diazafluorene with salicylaldehyde. The interaction of Schiff base with different metal ions has been studied over photofluorescent spectra. The results showed that Schiff base exhibited 194-fold enhancements in fluorescence at 465 nm after Zn(2+) ions. Such fluorescent responses could be detected by naked eye under UV-lamp. The complex solution (L-Zn(2+)) exhibited reversibility with EDTA.
通过9,9-双(3,5-二甲基-4-氨基苯基)-4,5-二氮杂芴与水杨醛的席夫碱缩合反应合成了一种新型的基于4,5-二氮杂芴的荧光化学传感器。通过光荧光光谱研究了席夫碱与不同金属离子的相互作用。结果表明，席夫碱在加入Zn(2+)离子后，在465nm处荧光增强了194倍。这种荧光响应在紫外灯下肉眼即可检测到。配合物溶液（L-Zn(2+)）与EDTA表现出可逆性。
