A calix[4]arene lipoic acid (C4LA) was synthesized by click chemistry in 62% yield. It was immobilized on Au surfaces via self-assembly to offer C4LA Self-Assembled Monolayers (SAMs). The SAMs show wettability and electrochemical impedance dual-signal response for methomyl with highly sensitivity and selectivity.
