Photocontrolled surfaces have attracted increasing interest because of their potential applications in lithography, photopatterning, biointerfaces, and microfluidics. Light provides high spatiotemporal resolution to control functions of such surfaces without getting into direct contact. However, conventional photocontrolled surfaces can only be switched between two states (on and off). The development of photocontrolled reconfigurable surfaces that can be switched among multiple states is highly desirable because these surfaces can adapt to rapid environmental changes or different applications. Herein, recent developments of photocontrolled reconfigurable surfaces are reviewed. Specially, reconfigurable surfaces based on photocontrolled reversible reactions including thiol‐quinone methide, disulfide exchange, thiol‐disulfide interconversion, diselenide exchange, and photosubstitution of Ru complexes are highlighted. As a perspective, other photocontrolled dynamic bonds that can be used to construct reconfigurable surfaces are summarized. Remaining challenges in this field are discussed.

基于光控动态键的可重构曲面

光控表面由于其在光刻，光图案，生物界面和微流体学中的潜在应用而引起了越来越多的兴趣。光提供了高时空分辨率，可以控制此类表面的功能，而无需直接接触。但是，常规的光控表面只能在两种状态（打开和关闭）之间切换。迫切需要开发能够在多种状态之间切换的光控可重构表面，因为这些表面可以适应快速的环境变化或不同的应用。在此，回顾了光控可重构表面的最新发展。特别是基于光控可逆反应的可重构表面，包括硫醇醌甲基化物，二硫键交换，硫醇二硫键相互转化，二硒化物交换和Ru配合物的光解被强调。作为一个角度，总结了可用于构造可重构表面的其他光控动态键。讨论了该领域中尚存的挑战。
