Abstract:
UV-induced disulfide formation (UV-DF) and disulfide reduction (UV-DR) reactions for surface functionalization and dynamic photopatterning are presented. Both photochemical reactions allow for the spatially and temporally controlled, reversible transition between thiol- and disulfide-functionalized surfaces. The dynamic photopatterning strategy was demonstrated by the UV-induced attachment, exchange, and detachment on thiol-modified substrates.
