C3n
C3n is a term used in chemistry and materials science to denote a class of carbon-nitrogen compounds with a general empirical formula that can be written as C3Nn. The exact chemical identity of C3n is not fixed; depending on the value of n and the arrangement of atoms, it can refer to different structures, including discrete molecules, polymeric networks, or extended two-dimensional sheets.
In discussions of carbon-nitride chemistry, C3n serves as a placeholder for structures containing predominantly carbon and
Predicted properties of C3n-class materials are heterogeneous and largely theoretical. Many studies propose tunable electronic structures,
Synthesis of concrete C3n materials remains a developing area. Research is predominantly computational or exploratory, aiming
