Molecular Recognition of Biologically Relevant Anions with an Expanded Dinuclear Copper(II) Complex: An Efficient Sensor for Oxalate Anion in Aqueous Solution
Abstract:An expanded dinuclear copper(II) complex (1) derived from a biphenyl‐based hexaazamacrocyle (L) was synthesized and characterized by single crystal X‐ray analysis, exhibiting a boat‐shaped cavity with an elongated CuII⋅⋅⋅CuII distance of 11.01 Å. The dinuclear copper(II) complex was investigated for a verity of biologically relevant anions including carboxylates (oxalate, citrate, tartrate, glutamate, adipate, acetate and benzoate), oxoanions (phosphate, sulphate, perchlorate and nitrate), and halides (fluorid… Show more
