Synthesis of Schiff Base Bearing Phenolic Hydroxy Group and Its Anion Recognition
- Received Date: 2011-03-09
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.
