Abstract

This paper describes the synthesis of poly-[4-[(3,5-di-tert-butyl-4-hydroxyphenyl) (3,5-di-tert-butyl-4-oxocyclohexa-2,5-dien-1-yldene) methyl]phenylacetylene] (abbreviated as poly[(p-ethylphenyl)hydrogalvinoxyl]) (4) and also the formation of its polyradical macromolecule, 5, through chemical oxidation. 5 is one of the model polymers with an indirect magnetic interaction; the unpaired electron is mainly localized at the phenylgalvinoxyl side chain, whose spin density is distributed mainly over the galvinoxyl substituent, but also over the phenyl ring to some extent by a spin polarization mechanism.
