Ultrasensitive electrochemical detection of bisphenol A using copper(ii) metal-organic framework ternary quantum dot (Cu-MOF/TQD) composite-modified gold electrodes.

ABSTRACT: A copper(ii) metal-organic framework (MOF) formulated as [Cu₄(NITA)₄(H₂O)₂(DMF)₄]·(DMF)₄ was prepared and characterized by single-crystal X-ray crystallography. The compound crystallized as a paddled wheel binuclear complex with each copper(ii) ion in a distorted square pyramidal geometry. The MOF was reacted with silver indium sulphide (AgInS₂) ternary quantum dots (TQDs), prepared using a hydrothermal technique, to construct a composite electrochemical sensor, formulated as {AgInS₂@[Cu₄(NITA)₄(H₂O)₂(DMF)₄]·(DMF)₄} with improved electrochemical performance. The composite was characterized by electron microscopy and spectroscopic techniqu
