We synthesized new chiral all-organic liquid crystalline (LC) compounds with nitroxide (NO) and hydroxy (OH) groups, which form intermolecular hydrogen bonds between the NO and OH groups. The LC compounds show hexagonal columnar phases at room temperature, which solidify as LC glasses at low temperature. The experimental magnetic susceptibility of each of the compounds in the LC and isotropic phases is larger than that theoretically estimated on the simple assumption about the amount of the spins, whereas it accords with the theoretical one in the LC glass state. It is called magneto-LC effects. The difference between experimental and theoretical magnetic susceptibilities gradually increases as temperature increases through the LC glass state-to-LC phase transition. It suggests that molecular mobility is one of the origins of the magneto-LC effects.

分子迁移率对一氧化氮自由基作为氢键受体的全有机顺磁性液晶相互作用的影响

我们合成了具有氮氧化物（NO）和羟基（OH）基团的新型手性全有机液晶（LC）化合物，它们在NO和OH基团之间形成分子间氢键。LC化合物在室温下呈六方柱状相，在低温下会固化为LC玻璃。LC和各向同性相中每种化合物的实验磁化率均大于理论上基于对自旋量的简单假设得出的理论磁化率，而与LC玻璃态下的理论磁化率相符。这称为磁LC效应。随着温度的升高，通过LC玻璃状态到LC的相变，实验磁化率和理论磁化率之间的差异逐渐增大。
