Abstract

Abstract : Copper(ii )-containing metal–organic xerogels (Cu-MOXs), was produced and Cu-MOXs can catalyze the chemiluminescence of luminol–H2 O2 system. Dopamine can be detected with the inhibition effect on Cu-MOXs–luminol–H2 O2 system. Abstract : In this work, copper(ii )-containing metal–organic xerogels (Cu-MOXs), which were composed of copper as the central ion and 2, 2′-bipyridine-6, 6′-dicarboxylic acid as the ligand, were quickly synthesized by a mild facile strategy. The Cu-MOXs exhibited superior catalytic performance for the luminol–H2 O2 chemiluminescence (CL) system. The possible mechanism was studied via CL spectra, UV-Vis absorption and electron paramagnetic resonance (ESR). Since dopamine (DA) can inhibit the reaction of this system, a sensitive paper-based CL device for the detection of DA was established. Under the optimal experimental conditions, the linear range of this method was 40–200 nM with a detection limit of 10 nM. The proposed method was used for the determination of DA in urine samples.
