Selenium is an essential element to human body. Our research group has recently revealed many unique features of selenium-containing bonds. For instance, diselenide bond has dual redox response, and it is also a type of dynamic bond which can undergo exchange reaction under visible light irradiation. Combing those interesting properties of selenium-containing bonds with surface/interface chemistry can endow system with unique responsive behaviors. This article reviews the recent progresses we made in the field of selenium-containing surface/interface chemistry. We used single molecule force spectroscopy to study the nature of selenium-containing bonds in the force point of view, and used interface chemistry to modulate the equilibrium of diselenide dynamic exchange reaction. Additionally, we achieved reversible surface modification, two- dimensional material functionalization and layer-by-layer nanocomposite film fabrication based on the redox and light response of diselenide bond, which may find potential applications in fields like biomedical research and liquid transfer.
