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.
