Abstract

A reversible surface functionalization and patterning strategy based on a photodynamic disulfide exchange reaction is demonstrated. The method allows for rapid and reversible functionalization, patterning, and exchange or removal of functional groups on the surface.

Keywords: disulfide exchange; patterning; photochemistry; rewritable surfaces; surface functionalization.
