Resorcin[4]arene-based microporous metal–organic framework/reduced graphene oxide composite as an electrocatalyst for effective and simultaneous determination of p-nitrophenol and o-nitrophenol isomers

We herein reported a newly microporous metal–organic framework (MOF), [Mn4(TPTR4A-II)0.5(bpdc)4(H2O)]·2DMF (Mn-MOF) (bpdc = biphenyl-4,4′-dicarboxylate, DMF = N,N′-dimethylformamide), constructed by bpdc anions, Mn(II) cations and a novel functionalized resorcin[4]arene (TPTR4A-II). For the first time, Mn-MOF was immobilized on graphene oxide (GO) to give [email protected] composite. During the electrochemical experiments, the reduced graphene...
