Abstract

Abstract: Four novel ferrocenyl long -chain-alkyl β-diketonato zinc(Ⅱ)complexes with a general formula ZnL₂(L=C₅H₅FeC₅H₄COCHCOC_nH_2n+1, n =6～9)were prepared by reaction of ferrocenyl long chain-alkyl β-diketones with Zn(CH₃COO)₂·2H₂O. These complexes were characterized by elemental analysis, IR, ¹H NMR, MS and TG DTA. The results studied by DSC and polarizing microscopy with a heating stage show that the four heteronuclear transition metal complexes have thermotropic liquid crystalline properties. This type of liquid crystalline complexes has not been reported so far.

Key words: ferrocene, β-diketonato zinc(Ⅱ)complex, liquid crystal, preparation
