Magnetic Alignment Induced by the Well-Designed Nano-Structure of Chiral Polyradials and their Magneto-Optical Property

以稳定的自由基为磁源的多自由基，由于其分子设计可以调控各种性质，因此有望成为新型磁性材料的候选者。例如，新的磁光性能将被期望与他们的单手螺旋结构相结合的多自由基。我们已经成功地合成了具有过量单手螺旋结构的手性多自由基，并发现一些多自由基通过形成螺旋构象而增加了它们的反铁磁性质。

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.
