PURPOSE:To exhibit ferromagnetism in polyacetylene derivative by holding polymer synthesized by polymerizing specific monomers at Curie temperature or lower for a predetermined time. CONSTITUTION:Polymer synthesized by polymerizing monomers represented by formula I is held in a temperature range of ferromagnetism exhibiting temperature and Curie temperature for a predetermined time. In formula I, R1, R2 are hydrogen atom, halogen atom, alkyl group, cycloalkyl group, aryl group, heterocyclic group, aromatic cyclic group, etc., and at least one of the R1, R2 is a substituted or unsubstituted aromatic ring or heterocyclic ring. Thus, ferromagnetism can be exhibited in polyacetylene derivative without complicate synthesis or process. |
