title: Immobilisation of photoswitchable diarylcyclohexenes synthesised via cobalt-mediated Diels-Alder reaction.
abstract: Functionalised photoswitches--photochromic dithienylcyclohexenes--were prepared in two steps by a cobalt-mediated Diels-Alder reaction of internal alkynes with the isoprenylpinacolboronic ester. The three-component one-pot reaction sequence provides the photochromic dithienylcyclohexenes in up to 67% overall yield.
