Abstract

A new difunctional recognition and nanocatalytic probe of copper metal–organic framework surface molecularly imprinted polyethyleneimine (CuMOF@MIP) was prepared by microwave procedure, using tert-butylhydroquinone (TBHQ) as the template molecule, CuMOF as the nanosubstrate and polyethyleneimine (PEI) as the functional monomer. The experimental results demonstrate that the CuMOF@MIP nanoprobes exhibit strong catalysis of acrylic acid reduction of silver nitrate to produce silver nanoparticles (AgNP) with surface plasmon resonance Rayleigh scattering (RRS) effect at 330 nm. The new nanocatalytic amplification indicator reaction was studied by RRS and coupled with the recognition function to develop a catalytic analysis strategy. The RRS peak increased linearly with increasing TBHQ analysis. Thus, a new, simple, and sensitive RRS analytical platform was developed to determine TBHQs in cooking oil, with the relative standard deviations (RSDs) of 2.05–6.76 % and the recovery of 92.5–108 %.

期刊介绍： Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
