摘要: 金属配合物液晶的分子设计与合成,是近10年来液晶学科的一个新的研究领域[1,2]. 文献已报道的过渡金属液晶配合物多为单核或同核,而异核过渡金属液晶的研究甚少。

Abstract: Four novel ferrocenyl long -chain-alkyl β-diketonato zinc(Ⅱ)complexes with a general formula ZnL2(L=C5H5FeC5H4COCHCOCnH2n+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.
