Carbon nitride, usually described as C3N4 or CNx (x>1), has been reported to form disordered network structures. In this work we describe a new synthesis route using 2-amino-4,6-dichloro-s-triazine (ADCT) as a single-source precursor, adopting single step and two step decompositions. During two step polycondensation ADCT is first heated in a closed system and than fully condensed under vacuum. Our reactions yielded carbon nitride materials having compositions near C3N4. The obtained carbon nitride occurs as a brown, amorphous solid according to X-ray and electron diffraction experiments. Moreover, infrared spectra and results from C-13-NMR measurements indicate evidence for the presence of bridged heptazine and triazine units in the structure. (C) 2008 Elsevier B.V.
