✦ Synopsis

Carbon nitrides are of current interest due to their novel mechanical, optical, and tribological properties including low density, surface roughness, wear resistance, chemical inertness, and biocompatibility. [1][2][3][4] These superhard diamondlike materials promise a variety of technological and biological applications, for example, biocompatible coatings on biomedical implants, [5][6] battery electrodes, [7][8] gas-separation systems, [9] corrosion protection, [10] and humidity and gas sensors. [11] As these applications are primarily governed by the particle size, material texture, and nitrogen content, an extensive effort has focused on the discovery of precursors along with appropriate methods to control the size, regulate the texture, and increase the nitrogen content of carbon nitrides. We report here three novel nitrogen-rich nanolayered, nanoclustered, and nanodendritic carbon nitrides that were prepared from 4,4',6,6'-tetra(azido)azo-1,3,5-triazine (TAAT), a member of a unique class of high-nitrogen C,N-containing energetic materials.
