carbontonitrogen

Carbontonitrogen is a term used to describe a class of carbon-nitrogen materials that would form extended covalent networks of carbon and nitrogen atoms. The phrase is not tied to a single well-defined compound and in the literature is sometimes used loosely to describe hypothetical CN frameworks or, in some sources, to refer to graphitic carbon nitride (g-C3N4), a well-studied material with a C3N4 composition.

Structure and bonding: Theoretical models typically depict carbon and nitrogen in sp2- or sp-hybridized networks, producing layered or three-dimensional frameworks. Predicted properties vary with composition and topology, but many models anticipate a wide band gap, high thermal and chemical stability, and relatively low carrier mobility.

Synthesis and occurrence: There is no broadly accepted laboratory synthesis of a pure carbontonitrogen solid as of now. Proposed routes in speculative literature include polymerization of small CN building blocks under controlled temperatures and pressures, or chemical vapor deposition using nitrogen-rich carbon precursors. Real-world materials with CN motifs, such as graphitic carbon nitride, are sometimes discussed in this context.

Applications and research status: Carbontonitrogen remains largely theoretical and exploratory. If realized, potential applications could include wide-band-gap semiconductors, photocatalysts for solar energy conversion, or protective coatings. Experimental verification, synthesis methods, and safety considerations are active topics of investigation.

Carbontonitrogen is not a standard material in chemical catalogs, and its definition varies across sources.
