  bibo_abstract:
  - Donor–acceptor Stenhouse adducts (DASAs) are visible‐light‐responsive photoswitches
    with a variety of emerging applications in photoresponsive materials. Their two‐step
    modular synthesis, centered on the nucleophilic ring opening of an activated furan,
    makes DASAs readily accessible. However, the use of less reactive donors or acceptors
    renders the process slow and low yielding, which has limited their development.
    We demonstrate here that 1,1,1,3,3,3‐hexafluoro‐2‐propanol (HFIP) promotes the
    ring‐opening reaction and stabilizes the open isomer, allowing greatly reduced
    reaction times and increased yields for known derivatives. In addition, it provides
    access to previously unattainable DASA‐based photoswitches and DASA–polymer conjugates.
    The role of HFIP and the photochromic properties of a set of new DASAs is probed
    using a combination of <jats:sup>1</jats:sup>H NMR and UV/Vis spectroscopy. The
    use of sterically hindered, electron‐poor amines enabled the dark equilibrium
    to be decoupled from closed‐isomer half‐lives for the first time.@eng
