Preparation of carbon nitride C2N by shock-wave compression of poly(aminomethineimine)

Abstract

Shock-wave compression of poly(aminomethineimine) under a pressure of 40 GPa produced no crystalline material but amorphous carbon nitrides having microscopically different morphologies, a quasi-spherically concentric closed-shell form, a random-layer-structure and a completely amorphous structure. These have the same composition, C₂N, and the same chemical structure consisting of sp² carbon and sp² nitrogen.
