基盤研究(B)
We have achieved the synthesis of various neutral or ionic chiral radical liquid-crystalline (LC) compounds which have a nitroxide unit in the central portion of the molecule. Furthermore, we have observed the generation of spin glass-like strong magnetic interactions in their LC phases under weak magnetic fields. By means of electron paramagnetic resonance spectroscopy which is favored for the magnetic measurement at high temperatures, the relationship between the molecular and LC layer structures and the magnetic interactions has been clarified. Based on these results, the mechanism of the generation of unique magnetic interactions in the LC phases has been proposed.
