设计合成了一种含酚羟基Schiff碱类受体1-羟基-4-氯-二苯甲酮-2,4-硝基苯腙受体分子1. 利用紫外-可见吸收光谱、荧光光谱考察了其与AcO, , F, Cl, Br, I等阴离子的作用. 当加入AcO, F和 时, 导致紫外光谱的可见光区明显变化(大约130 nm红移), 同时伴随着从亮黄色到粉红色的“裸眼”颜色变化. 通过在DMSO-d6核磁滴定实验进一步研究了探针1和F相互作用的本质.

A new anion receptor bearing phenolic hydroxy group based on Schiff base 1-hydroxy-4-chlo-ride-2,4-nitro-phenylhydrazonocarboxy (1) was designed and synthesized. The binding properties of the receptor with anions such as AcO, , F, Cl, Br, I were investigated by UV-Vis and fluorescent titrations. Addition of AcO, , F results in a noteworthy change in the visible region of spectrum (approximately 130 nm red shift), accompanied by visible color changes from light yellow to pink, which can be detected by the “naked-eye”. The further insights to the nature of interactions between the sensor 1 and F were investigated by 1H NMR titration experiments in DMSO-d6.
