The three new ferrocenyl β diketones and their nickel(Ⅱ)complexes with a general formula NiL 2·2H 2O(L=C 5H 5FeC 5H 4COCHCOC n H 2n+1 , n =11,13,15) were synthesized.These β diketones and nickel (Ⅱ) complexes were characterized by elementary analysis,IR, 1HNMR,MS and TG DTA.The liquid crystalline behavior of the complexes was studied by DSC and polarizing microscopy with a heating stage.It was found that the nickel (Ⅱ) complexes have smectic thermotropic liquid crystalline properties.
