Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A photoreversible switch based on a photoresponsive host–guest system consisting of dimethylamino calix[4]arene <bold>L</bold> and 4‐(phenylazo)benzoic acid (<bold>O</bold>) is reported. The host <bold>L</bold> exhibited selective binding and release of <bold>O</bold> 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.</p> </abstract>
