| Research Abstract |
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 chiral polyradicals with excess of one-handed helical structure, and found that some polyradicals increased their antiferromagnetic properties by forming helical conformation.
