Intramolecular B–N Coordination as a Scaffold for Electron‐Transporting Materials: Synthesis and Properties of Boryl‐Substituted Thienylthiazoles

Stacking the deck: Incorporation of boryl groups into the thienylthiazole system fixes the π-conjugated framework in a planar fashion by intramolecular B–N coordination. The dimer of boryl-substituted thienylthiazole forms a unique packing structure with offset face-to-face π stacking (see picture; B orange, N blue, S yellow, C turquoise) and films of it show high electron mobility.
