Abstract

A high-surface-area silicon oximide-based gel [SiOC(H)=NSi]_m[Si₂N-C(H)=O]_n[SiN(H)-C(H)=O]_p[SiOC(H)=NH]_q[SiNH]_r[SiNH₂]_s[SiNMe₂]_t was prepared via a formamide-based aminolysis of tris(dimethylamino)silylamine, (Me₂N)₃SiNH₂. The structure of the gel and the mechanism of formation are elucidated. Pyrolysis of the gel at 1000 °C under N2 flow gave an amorphous microporous oxynitride-based glass with a BET surface area of 195 m2 g⁻¹.
