Microporous polymers based on triacetylarenes

Three-dimensional polymers are synthesized by polycondensation of triacetylarenes with the formation of 1,3,5-phentriyl and dimeric diphenylpropenone fragments. Microporous polyphenylenes with an intrinsic surface area of 650–690 m² g^–1 were obtained by additional heating at 450 °C. The values of the intrinsic surface area of polyphenylenes with rigid-chain rod-shaped inter-nodal fragments significantly exceed those of polyphenylenes with a flexible-chain inter-nodal fragments.
