丝状液晶与铁卟啉的配位作用

Coordination Between Nematic Liquid Crystal and Iron Porphyrins

研究了掺杂5,10,15,20-四苯基铁(Ⅲ)叶啉氯化物(Fe(TPP)Cl)的丝状液晶5CB在光场下的弗雷德里克兹转变和其Uv-vis光谱.掺杂Fe(TPP)Cl,能有效地降低液晶5CB在光场下发生弗雷德里克兹转变的阈值.Fe(TPP)Cl的Soret带随着液晶5CB含量增大而红移.这是液晶5CB与Fe(TPP)Cl发生轴向配位的结果.

The optical-induced Freedericksz Transition and Uv-vis spectra of nematic liquid crystal 5CB doped with 5,10, 15, 20-tetraphenylporphyrinairon(III) chloride [ Fe(TPP)Cl] have been studied. Liquid crystal 5CB doped with Fe(TPP)Cl dramatically decreased the critical optical field. The soret hand of Fe(TPP)Cl were red shift to some extent with the increase of the proportion of 5CB. They are resulted from the axial coordination between 5CB and Fe(TPP)Cl.
