The recognition of the mercury(II) ion (Hg2+) is essential because of its extreme toxicity in the environment and food. Hence we reported a novel cysteine (Cys) complex of-piperidine-calix[4]arene (L) as a-convenient and effective dual-signal responsive switch for Hg2+. This switch system exhibited excellent selectivity toward Hg2+ by fluorescence (FL), H-1 NMR spectroscopy and the atomic force microscopy (AFM). More importantly, the Hg2+-responsive switch had an important and potential application by water contact angle (CA) on a functional micro nano silicon surface, including intelligent microfluidic and laboratory-on-chip devices, controllable drug delivery, and self-cleaning surfaces.
