Polycondensation/pyrolysis of tris-s-triazine derivatives leading to graphite-like carbon nitrides

Polycondensation/pyrolysis of 2,5,8-tricarbodiimide-tris-s-triazine and its derivatives gave hexagonal graphite-like pseudo carbon nitrides, CH0.3-0.08N1.0-0.63, composed of tris-s-triazine nuclei. The materials were stable up to 600-800 degreesC under an inert atmosphere depending on their nitrogen content.
