摘要

Hydrazone-based receptor containing electron-withdrawing chromogenic substituents 1,10-phenanthroline-2,9-di-carboxaldehydic-(2,4-dinitrophenyl)-hydrazone (1) has been synthesized. The interaction with different anions via hydrogen bonding was demonstrated by UV-Vis absorption spectroscopy to give a purple 1:1 complexes in DMSO, whose association constant decreases in line with the following order of the studied anions (AcO- > F- > H2PO4 (-) > OH- >> Cl-similar to Br-similar to I-). As a naked-eyes colorimetric sensor for anions, the study has a latent application importance.
