摘要
A new anion receptor bearing phenolic hydroxy group based on Schiff base 1-hydroxy-4-chloro-2,4-nitro-phenylhydrazonocarboxy (1) was designed and synthesized. The binding properties of the receptor with anions such as AcO-, (HPO4-)-P-2, F-, Cl-, Br-, I- were investigated by UV-Vis and fluorescent titrations. Addition of AcO-, H2PO4-, 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 H-1 NMR titration experiments in DMSO-d(6).
