Tetrazolo[1,5-a]pyridine-Containing π-Conjugated Systems: Synthesis, Properties, and Semiconducting Characteristics

Abstract

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.

Synthesis, antimicrobial activity and application of polymers of praseodymium complexes based on pyridine nitrogen oxide

“…[6][7][8] Pyridine nitrogen oxides are a class of common organic compounds containing pyridine, which are extensively utilized in pharmaceutical synthesis and other elds due to their diverse synthesis pathways, superior biological activity, ease of synthesis, and excellent chelating ability. [9][10][11][12][13][14][15][16][17][18][19][20][21] Literature reports have demonstrated that complexes of pyridine nitrogen oxides and transition metals exhibit considerable anticancer and antibacterial activities, 22,23 making them valuable in biomedicine and as antimicrobial materials.…”
