Ordered and amorphous microporous polytriazine networks have been obtained from the trimerization of nitriles in a ZnCl2 melt at 400 °C (see structure of the polymer formed from 1,4-dicyanobenzene; C gray, N blue). The materials are high-performance polymers with very large surface areas and could find applications in gas storage, as sensors, or catalyst supports.
