Benefiting from the integration of electrospun polyacrylonitrile (PAN) nanofibers and TFPB\u2010TAPB (2,4,6\u2010trihydroxybenzene\u20101,3,5\u2010tricarbaldehyde [TFPB] and 1,3,5\u2010tris(4\u2010aminophenylbenzene) [TAPB]), the composite mitigated the aggregation of conventional COF powders and provided accessible adsorption sites with good structural stability. The as\u2010prepared PAN@TFPB\u2010TAPB sorbent exhibited higher extraction efficiency toward seven organophosphate esters (OPEs) compared with pure PAN and TFPB\u2010TAPB. On this basis, a sensitive and reliable TFME\u2010gas chromatography\u2010mass spectrometry method was established for the simultaneous enrichment and determination of OPEs in degradable plastic samples. Under the optimal conditions, the proposed method displayed wide linear ranges, low limits of detection, good precision, and satisfactory recoveries. Furthermore, this method was successfully applied to the analysis of OPEs in real complex plastic samples, demonstrating its great practical potential for the efficient monitoring of OPEs in environmental and commodity\u2010related matrices.<\/jats:p>","DOI":"10.1002\/jssc.70551","type":"journal-article","created":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T05:58:36Z","timestamp":1791525516000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["In\u2010situ Grown Covalent Organic Frameworks on Electrospun Nanofibers for Efficient Enrichment and Determination of Organophosphate Esters in Biodegradable Plastics"],"prefix":"10.1002","volume":"49","author":[{"given":"Xinrui","family":"Tian","sequence":"first","affiliation":[{"name":"College of Chemistry, Beijing Key Laboratory of Environmentally Harmful Chemical Analysis Beijing University of Chemical Technology  Beijing P.
