含有顺磁性过渡金属离子的金属介晶是人们感兴趣的,因为这些介晶相的取向可以通过磁场来控制。报道了第一种顺磁性含Ni液晶(与图中所示的非介晶化合物相关)。讨论了它们复杂的温度依赖性磁行为,并表明其反映了镍配位核的变化。
Metallomesogens containing paramagnetic transition metal ionsare of interest because the orientation of these mesophases can be controlled by a magnetic field. The first paramagnetic Ni‐containing liquid crystals (related to the non‐mesogenic compound shown in the Figure) are reported. Their complicated temperature‐dependent magnetic behavior is discussed and shown to reflect changes in the coordination core of nickel.
