Abstract: On the basis of p-diacetylbenzene and 4,4'-diacetylbiphenyl, polyphenylenepyridines with a ratio of pyridine to phenylene rings of 1 : 5–6.5 were synthesized. Their heating in argon at 450, 800 and 1000 °C afforded porous polymers with a specific surface area up to 1146 m² g^–1. X-ray photoelectron spectroscopy of these substances showed that nitrogen atoms in them exist mainly in the form of graphite- and pyridine-like systems.

Keywords: polyphenylenepyridines, p-diacetylbenzene, 4,4'-diacetylbiphenyl, pyrolysis, pyropolymers, porosity, specific surface area, X-ray photoelectron spectroscopy.
