Synthesis and Structure of 2,5,8-Triazido-s-Heptazine: An Energetic and Luminescent Precursor to Nitrogen-Rich Carbon Nitrides

摘要

Aromatic nitrogen heterocycles have a wide variety of uses in coordination chemistry and optical science. As one example, the 1,3,5-triazine ring motif (s-triazine, C_3N_3) has shown extensive utility in synthetic chemistry,1 coordination chemistry,2 and optical and magnetic studies.3 Over the past few years, s-triazine has played a key role in molecular routes to carbon nitride (CN_x) materials investigated by various groups,4 including ours.5 Several of our triazine ring precursors contrast with those of others in that they are energetically unstable and rapidly decompose to CN_x materials.
