Outline of Final Research Achievements

Polyradicals which have stable radicals as magnetic source will be possible candidates for new magnetic materials, because various properties can be programmed by their molecular design. For example, new magnetooptical properties will be expected for the polyradicals in combination with their one-handed helical structure. We have succeeded in synthesizing helical polyradicals whose stable one-handed helical structure and magnetic alignment are programmed by their monomer sequences, and found that their antiferromagnetic properties were controlled by their monomer sequences.
