Abstract:
A new anion receptor bearing phenolic hydroxy group based on 3,5-ditertbutylsalicylaldehyde-p-nitrophenylhydrazone (1) was designed and synthesized. Upon addition of AcO- and F-, the receptor exhibited visible color changes from deep yellow to purple. However, no obvious color changes were observed on addition of the other anions tested (H2PO4-, Cl-, Br-, I-). The binding properties of the receptor with anions such as AcO- and F- were investigated by UV-Vis and fluorescent titrations. The result indicated that the receptor 1 had a higher affinity to AcO- and F- and a 1:1 host-guest complex was formed through H-bond interactions between 1 and anions.

摘要:
设计和合成一个基于3,5-二叔丁基水杨醛-p-硝基苯腙含酚羟基的新型阴离子受体1. 在加入AcO-和F-后,受体1发生从深黄色到紫色的颜色变化. 然而,在加入其它阴离子(H2PO4-, Cl-, Br-, I-)没有明显的颜色变化. 通过紫外和荧光滴定研究了受体与AcO-和F-结合的性质.
