研究了掺杂1.0wt%抗磁性卟啉锌(II)的平面取向向列相液晶的磁场诱导Fredericksz相变。结果表明，与纯5CB相比，掺入1.0wt%不同取代基苯环上的Zn(II)TPP-5，10，15，20-tetraphenyl-porphyrinatozinc(II)-衍生物的5CB具有陡峭的Fredericksz转变曲线，临界磁场显著降低。
The magnetic-field-induced Freedericksz transition of a planar aligned nematic liquid crystal doped with 1.0 wt % of a diamagnetic porphyrinatozinc(II) has been studied. It was observed that 5CB doped with 1.0 wt % of derivatives of Zn(II)TPP-5,10,15,20-tetraphenyl-porphyrinatozinc(II) - which have different substituents in one phenyl ring display sharp Freedericksz transition curves and dramatically decrease the critical magnetic field compared with pure 5CB.
