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。
The dinuclear copper complex [Cu (21)] 4+, which is a bis-naphthol double Schiff base compound, was designed and synthesized, which was used as the acceptor of the dicarboxylic acid anion and chrome azure S to form the chemical Sensing system. The chemical recognition of dicarboxylic acid anions in aqueous solution (HEPES 10 mM, pH = 7.0) was studied using indicator replacement method. The established chemical sensing system has good selectivity to malonate, while the other coexisting dicarboxylic acid anions have no obvious interference on the recognition of malonate.
