Axial Coordination Between Nematic Liquid Crystal 5CB and Fe(Ⅲ) Porphyrins

Abstract

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
