Provided are triarylamine derivatives excellent in compatibility with various organic solvents or resins, capable of forming a silicon-oxygen bond on the surface of an inorganic material, and allowing easy purification; a preparation process of the triarylamine derivative; an intermediate product of the triarylamine derivative; an inorganic composite material obtained by bonding the triarylamine derivative to the surface of an inorganic material; and a preparation process of the inorganic composite material.

Silanol-containing triarylamine derivatives

A solid material is subjected to surface treatment by chemically bonding onto a surface of the solid material a stabilized monofunctional silanol represented by RRRSiOH. R, Rand Rmay be the same or different, and each represent a substituent group independently selected from a substituted or unsubstituted, monovalent hydrocarbon group having from 1 to 40 carbon atoms or a substituted or unsubstituted, monovalent heterocyclic group having from 1 to 100 carbon atoms. The monofunctional silanol has a dehydrative self-condensation rate lower than triethylsilanol.
