摘要：
Calix[4] pyrrole based anion receptors 1 and 2 have been synthesized. The recognition and sensing process has been studied by UV-vis absorption and partial H-1 NMR titration experiments. Receptor 1 could act as a colorimetric sensor for fluoride anions, and receptor 2 could recognize F- and AcO- anions in DMSO solvent. Moreover, this type of sensing behaviour could successfully mimic a molecular level keypad lock stimulated by the two sequential chemical inputs (AcO- and F-), which has the potential for application in security devices.
