Rapid　and　convenient　preparation　of　covalent　organic　framework　(COF)　coated　fibers　is　of　great　significance　to　solid-phase　microextraction　(SPME)　technology.　In　this　work,　a　novel　chemical　preparation　strategy　was　established　for　rapid　fabrication　of　β-ketoenamine-linked　COF　coatings,　in　which　clay-like　starting　materials　of　COFs　were　first　wrapped　on　the　fiber　surface　through　self-viscosity　and　further　fixed　on　the　fiber　in　an　oven　via　chemical　bonding.　Based　on　this　strategy,　four　different　COF　(TpTph,　TpPa-1,　TpBD　and　TpTpb)　coated　fibers　was　fabricated　within　1　h,　which　is　very　rapid　compared　to　the　recently　reported　research.　Moreover,　the　strategy　also　demonstrates　the　good　general　applicability　for　COF　fiber　preparation.　Subsequently,　the　TpTph　coated　fiber　was　used　to　develop　a　new　SPME　method　for　gas　chromatography-tandem　mass　spectrometry　(GC-MS/MS)　of　trace　phthalic　acid　esters　(PAEs)　in　environmental　water.　The　developed　analytical　method　compared　to　the　previous　SPME　methods　for　PAEs　based　on　other　sorbents　possesses　low　limits　of　detection　(LODs,　0.02–0.08　ng　L−1),　and　better　or　comparable　precision　(RSD　≤9.4%,　n　=　6),　and　relatively　short　extraction　time.　Furthermore,　the　trace　PAEs　(0.27–11.62　ng　L−1)　in　the　real　water　samples　were　successfully　detected　with　recoveries　of　82.2–117.5%.　The　above　results　indicates　that　the　proposed　fiber　preparation　strategy　is　reliable　and　opens　a　potential　avenue　for　rapid　and　facile　fabrication　of　COF　coated　fibers.　©　2022　Elsevier　B.V.
