摘　　要：设计合成了以联二萘酚类双希夫碱化合物为配体的双核铜配合物[Cu(21)]4+,用其作为二元羧酸阴离子的受体与铬天青S构筑了化学传感体系。采用指示剂置换法,研究了该化学传感体系在水溶液中(HEPES10 mM,pH=7.0)对二元羧酸阴离子的识别作用。所确立的化学传感体系对丙二酸根具有良好的选择性,其它共存的二元羧酸阴离子对丙二酸根的识别过程无明显干扰。Dinuclear copper complex [Cu2（1）]4＋ was prepared by using new binaphthol derivative 1 as ligand,which was used as dicarboxylate receptor in water solution at pH 7.0.A chemosensing ensemble（CE） was constructed by mixing [Cu2（1）]4＋ and chromeazurol S with a molar ratio of 1：1.The dicarboxylate recognition properties of the ensemble was examined in water solution（HEPES 10 mM,pH=7.0）through indicator displacement-assays.CE exhibited a high selectivity toward malonate and the recognition process was barely interfered by other coexisting dicarboxylates.
