Description
Summary:The incorporation of an electron-accepting unit into π-conjugated systems is an important approach to modulate the physical properties of such molecules. To investigate the potential of tetrazolo­[1,5-a]­pyridine as an electron-accepting unit, a series of diarylated tetrazolo­[1,5-a]­pyridine derivatives was synthesized by treating the corresponding diarylated pyridine N-oxide with diphenylphosphoryl azide. Thermogravimetric analyses of these molecules indicated that they possessed good thermal stability. The bithiophene-substituted tetrazolo­[1,5-a]­pyridine compound showed stable transistor characteristics under repeated bias conditions.
