1,4,5,8,9,11-hexaazatriphenylene hexacarbonitrile HAT(CN)₆ represents a promising semiconductor material for organic electronic applications ranging from field-effect transistors to magnetic switches and solar cells. Herein, we report for the first time the application of HAT(CN)₆ for designing OFET-based gas sensors. The organic field-effect transistors based on HAT(CN)₆ showed a decent charge carrier mobility of 10⁻⁴ cm² V⁻¹s⁻¹ coupled with high sensitivity and fast response to low concentrations of ammonia. Quantum chemical DFT calculations were applied to investigate supramolecular interactions of HAT(CN)₆ with ammonia and reveal the origin of the observed sensing effect.
