摘要： 通过考察掺杂配位性质不同的两种铁(Ⅲ)卟啉的丝状液晶5CB在磁场下的行为以及UV-Vis光谱,研究了液晶5CB与铁(Ⅲ)卟啉的轴向配位作用.结果表明,弗雷德里克兹转变阈值的降低和Soret带随着液晶5CB含量增大而红移是液晶5CB与五配位Fe(TPCl发生轴向配位的结果.

关键词: 丝状液晶5CB, 铁(Ⅲ)卟啉, 配位作用, 弗雷德里克兹转变

Abstract: The axial coordination between nematic liquid crystal 5CBand iron(Ⅲ) porphyrins with different coordination properties was studied by the magnetic field induced Freedericksz Transition and UV-Vis spectra. The results indicated that 5CBdoped with five coordinated Fe(TPP)Cl dramatically decreased the critical magnetic field and the Soret band of Fe(TPP)Cl doped in 5CBhad red shift to some extent. These are resulted from the axial coordination between 5CBand five coordinated Fe(TPP)Cl.

Key words: Nematic liquid crystal 5CB, Iron porphyrin, Coordination, Freedericksz transition
