Properties and spectroscopic studies of polymeric dinitrosobenzenes

Abstract

Spectroscopic studies of the polymeric 1,4- and 1,3-dinitrosobenzenes show that the solid polymers are long chain and based upon the trans N₂O₂ group. The ‘ageing’ phenomenon reported elsewhere is not accompanied by any structural change that is detectable by the techniques employed. The importance of the solid state for stabilisation of the polymers is emphasised and it is shown that depolymerisation to the monomer (disubstituted benzenes containing two monomeric NO groups) occurs on heating and on vaporisation.
