Silicon substrates coated with a bromide-terminated silane are transformed into highly reactive, cyclopentadiene covered analogues. These surfaces undergo rapid cycloaddition reactions with various dienophile-capped polymers. Mild heating of the substrates causes the retro-Diels–Alder reaction to occur, thus reforming the reactive cyclopentadiene surface, generating an efficiently switchable surface.
