本文研究了掺杂不同顺磁掺杂剂的平面取向向列液晶（5CB）的磁场诱导重定向。结果发现，与纯5CB相比，掺杂五配位[Cu(o-xyTQ)H2O](NO3)2的5CB显着降低了重新取向的临界磁场强度，而掺杂六配位[Cu(DETQ)](ClO4)2的5CB则没有这种效应。尽管两种顺磁掺杂剂具有相同的磁性能，但它们与主体5CB具有不同的分子间耦合，从而产生不同的结果。这种现象对于研究液晶的磁光成分非常有用。
The magnetic-field-Induced reorientation of a planar alignment nematic liquid crystal (5CB) doped with different paramagnetic dopants has been studied in this paper. It was observed that compared with the pure 5CB, 5CB doped with five-coordinated [Cu(o-xyTQ)H2O](NO3)2 dramatically decreased the critical magnetic field strength for the reorientation, while 5CB doped with six-coordinated [Cu(DETQ)](ClO4)2 revealed no such effect. Although the two paramagnetic dopants possess the same magnetic property, they have different intermolecular couplings with host 5CB, which produce the different results. This phenomenon is very useful to study the magneto-optical component of liquid crystal.
