摘要

Novel calix[4]arene-based anion receptors 1-3 with bis-squaramide moieties were designed and synthesized. Their sensing properties with various anions were investigated by UV-vis, ESI-MS, and 1H NMR spectra. The experimental results revealed that there were two types of interaction modes where receptor 1 bound biologically important H2PO4-, F -, and AcO- ions selectively over other anions in the hydrogen bonding interaction mode, while receptors 2 and 3 displayed deprotonation behavior with basic anions (F-, AcO-, and H2PO4-) via acid-base interaction mode. Receptors 2 and 3 were proved to be efficient 'naked-eye' sensors for F - and AcO- with marked color changes.
