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.
