摘要：

Polyacetylene has been chemically modified by the incorporation of spin-labelled moieties. The magnetic properties were characterized by static magnetic susceptibility measurements and ESR spectroscopy. In spite of the very low spin concentrations of about 10-3 per CH unit employed, magnetic spin-spin interactions were observed. Magnetically correlated units consisting at least of pairs of spins with ferromagnetic exchange coupling (J/kB ≥ 8 K) were found in galvinoxyl-modified polyacetylene. © 1990.
