Paragraph 0151-0157, (2022/01/04)
The invention belongs to the technical field of organic materials, and provides a nitrogen-containing compound, an electronic component using the same and an electronic device. The structure of the nitrogen-containing compound is shown as a formula I; in the formula I, Ar1 and Ar2 are independently selected from substituted or unsubstituted aryl with the carbon atom number of 6-25, L1 and L2 are independently selected from a single bond, substituted or unsubstituted arylene with the carbon atom number of 6-25 and the like; and the nitrogen-containing compound can effectively improve the performance of the electronic component.

Photochemistry provides a sustainable pathway for organic transformations by inducing radical intermediates from substrates through electron transfer process. However, progress is limited by heterogeneous photocatalysts that are required to be efficient, stable, and inexpensive for long-term operation with easy recyclability and product separation. Here, we report that boron carbonitride (BCN) ceramics are such a system and can reduce organic halides, including (het)aryl and alkyl halides, with visible light irradiation. Cross-coupling of halides to afford new C-H, C-C, and C-S bonds can proceed at ambient reaction conditions. Hydrogen, (het)aryl, and sulfonyl groups were introduced into the arenes and heteroarenes at the designed positions by means of mesolytic C-X (carbon-halogen) bond cleavage in the absence of any metal-based catalysts or ligands. BCN can be used not only for half reactions, like reduction reactions with a sacrificial agent, but also redox reactions through oxidative and reductive interfacial electron transfer. The BCN photocatalyst shows tolerance to different substituents and conserved activity after five recycles. The apparent metal-free system opens new opportunities for a wide range of organic catalysts using light energy and sustainable materials, which are metal-free, inexpensive and stable.
