“…To further enhance the stability, the grown COF coating has been covered by a layer of polyimide (PI) by the dip-coating method. The COF@PI-coated fiber has demonstrated excellent enrichment efficiencies toward polybrominated diphenyl ethers (PBDEs), with EFs from 1470 to 3555 . The surface modified with APTES is likely to be universal for the in situ growth of COF coatings, which needs to be confirmed by subsequent studies.…”

“…The enhancement factors were 4471–7488; the detection limits (LODs) and quantification limits (LOQs) were 0.07–0.35 ng L –1 and 0.24–1.17 ng L –1 , respectively . Ouyang and co-workers synthesized a COF (TPB-DMTP) by condensation of TPB (1,3,5-tris (4-aminophenyl) benzene) and DMTP (2,5-dimethoxyterephthalaldehyde) . The PI@TPB-DMTP SPME fiber was prepared by coating TPB-DMTP and covering with an ultrathin layer of PI (polyimide) through a simple dip-coating method.…”

As an emerging porous crystalline organic material, the covalent organic frameworks (COFs) are given more and more attention in many fields, such as gas storage and separation, catalysis, energy storage and conversion, luminescent devices, drug delivery, pollutant adsorption and removal, analysis and detection due to their special advantages of high crystallinity, flexible designability, controllable porosities and topologies, intrinsic chemical and thermal stability. In recent years, the COFs are applied in analytical chemistry, for instance, chromatography, solid-phase microextraction, luminescent and colorimetric sensing, surface-enhanced Raman scattering and electroanalytical chemistry. The COFs decorated electrodes show high performance for detecting trace substances with remarkable selectivity and sensitivity, such as heavy metal ions, glucose, hydrogen peroxide, drugs, antibiotics, explosives, phenolic compounds, pesticides, disease metabolites and so on. This review mainly summarized the application of COF based electrochemical sensor according to different target analytes.

“…In recent years, covalent organic frameworks (COFs) have received great interest as a novel class of crystalline nanoporous materials. Because of their high surface area, uniformly adjustable apertures, permanent nanoscale porosities, and fascinating diverse structures, COFs have been demonstrated to be the ideal extraction materials in analytical chemistry. − More importantly, through the reasonable design of organic functional monomers, COFs can be endowed with additional optical, electrical, and magnetic properties while maintaining their own efficient extraction. − Thereinto, the facile strategy for improving the electrochemical performance of COFs has been studied preliminarily by introducing conductive active monomers. Classically, COFs constructed with monomers based on rigid conjugated planar macrocyclic molecules, such as porphyrin, thiophene, phthalocyanine, and tetrazolium, exhibit excellent electrical properties and electrocatalytic activity.…”

Electro-enhanced solid-phase microextraction (EE-SPME) is a bright separation and enrichment technique that integrates solid-phase microextraction with the electric field. It retains the excellent extraction performance of SPME technology while having the advantages of efficient driving of electric field and special interaction between the electric field and electrons in the molecules of material structure. Replacing conventional SPME fibers with highly efficient and highly conductive original EE-SPME fibers is critical for the practical applications of these technologies. Here, a novel fiber preparation strategy was proposed to obtain a highly conductive porphyrin-based covalent organic framework (POR-COF) by one-step electropolymerization. Benefiting from the excellent semiconducting properties of porphyrin groups, the POR-COF can be spontaneously polymerized on the fiber surface under an appropriate voltage within a few hours. Its performance was evaluated by the EE-SPME of phthalate esters (PAEs) from food and environmental samples, followed by gas chromatography−tandem triple quadrupole mass spectrometry (GC−MS/MS) technology. The results showed that the POR-COF fiber has been successfully used for the detection of trace PAEs in beverages, industrial wastewater, lake water, and oyster samples with high adsorption selectivity and satisfactory sensitivity. The remarkable extraction properties are mainly attributed to the synergistic effect from material characteristics and electrical parameters' control in the extraction process. The presented strategy for the controlled design and synthesis of highly conductive porphyrin-based covalent organic framework fibers offers prospects in developing EE-SPME technologies.
