title: Diastereoselective cyclization of a dithienylethene switch through single crystal confinement.
abstract: Upon UV irradiation of the hydrogen-bond confined crystal state of a dithienylhexafluorocyclopentene with (R)-N-phenylethylamide substituents, the photochemical cyclization reaction proceeds diastereoselectively to form the coloured, closed-ring isomer with 97% de.
