Four novel ferrocenyl long-chain alkyl U-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 U-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.
