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.
报道了一种基于光响应主客体体系的光可逆开关，该体系由二甲基氨基杯[4]芳烃L和4-(苯基偶氮)苯甲酸(O)组成。主体L分别在450和365 nm的紫外光和可见光照射下表现出对O的选择性结合和释放。此外，该光响应主客体复合物被用作功能微纳结构硅表面的光控润湿性开关，因此在传感器和微流控装置中有应用前景。
