Efficient Detection of Organophosphate Pesticide Based on a Metal−Organic Framework Derived from Biphenyltetracarboxylic Acid

A new conjugated metal−organic framework based on 2,2′,4,4′-biphenyltetracarboxylic acid with a uninodal five-connected hexagonal boron nitride net (bnn) was synthesized, which represented the first example of metal−organic frameworks capable of adsorbing a trace level of organophosphate pestcide for efficient detection via stripping voltammetric analysis. A detection limit of 0.006 μg·mL−1 was obtained with the calculation based on a signal−noise ratio equal to 3.
