A general concept for the preparation of junction‐point‐reactive, amphiphilic Y‐shaped block copolymer brushes for ultrathin polymer films is demonstrated, combining anionic polymerization techniques. The polymer films (1–3 nm) exhibit reversible, stimuli‐responsive wetting behavior upon application of different external stimuli (temperature and solvent). Contact angle measurements confirm the reversible hydrophobization with shifts up to 23°.
