A photoreversible switch based on a photoresponsive host–guest system consisting of dimethylamino calix[4]arene L and 4‐(phenylazo)benzoic acid ( O ) is reported. The host L exhibited selective binding and release of O on UV and visible irradiation at 450 and 365 nm, respectively. Moreover, the photoresponsive host–guest complex was applied as a photocontrolled wettability switch on a functional micro/nanostructured silicon surface, and is thus promising for applications in sensors and microfluidic devices.
