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