A ZnO‐based smart surface functionalized by a surface‐confined sub‐monolayer layer of a purpose‐built redox molecule is realized. The hybrid ferrocene/ZnO assembly exhibits a controllable wetting behavior with a contact angle that can be rapidly and reversibly adjusted to a defined value ranging from 110 ° to less than 10 ° (see figure).
