摘要 目的研究含手性基团的β-二酮及其铜(Ⅱ)配合物的合成及其性质.方法合成三种新的含手性碳原子的β-二酮,1-对辛(壬、癸)氧基联苯基-3-3′-甲基戊基-1,3-丙二酮,及它们的铜(Ⅱ)配合物.确定化学结构后,通过在偏光显微镜下进行相变观察以及作DSC分析,研究β-二酮及其铜(Ⅱ)配合物的相态变化.结果三种β-二酮配体均呈现双变S相液晶,而它们的铜(Ⅱ)配合物却没有表现出液晶性质.结论随着1-对烷氧基联苯基-3-3′-甲戊基-1,3-丙二酮配体的3位基团增大,它们的铜配合物的液晶性质消失. Aim To investigate the synthesis and properties of βdiketones and their copper(Ⅱ) complexes containing chiral substituents Methods Three new βdiketones (+)1(pnalkoxylbiphenyl)33′methylpentyl1,3dione,nalkoxyl:C8H 17 O,C9H 19 O,C 10 H 21 O and their copper (Ⅱ) complexes were prepared Their chemical stuctures were characterized and thermal behaviours were studied by polarizing microscope and differential scanning calorimetry Results The three ligands exhibit enantiotropic S mesophase and their copper (Ⅱ) complexes have no mesophase Conclusion The enlarged 33′methyl pentyl of the βdiketones results in the loss of mesophases of their Cu(Ⅱ) complexes 
