Synthesis of polymers based on acetylacenaphthen and 4,4′-diacetyldiphenyl oxide and study of their dehydrogenation by p-chloranil

Polycyclocondensation of acetylacenaphthalene and 4,4′-diacetyldiphenyl oxide or their ethyl ketals has been used to synthesize acenaphthene-containing oligopheyylenes and the possibility of obtaining from them acenaphthylene-containing oligophenylenes in a quite simple way has been explored. It is shown that treatment of the acenaphthene-containing oligophenylene with p -chloranil results in the formation of oligophenylenes containing π-complexes of acenaphthene fragments with p -chloranil. The spatial structuring of such oligophenylenes at 200–250°C is carried out through the reactions of the fragments indicated. Some properties of the three-dimensional polymers thereby formed are investigated.
