Phenolic　compounds　are　a　kind　of　persistent　organic　pollutants　(POPs),　which　are　always　a　threat　to　human　and　environment　due　to　their　strong　toxicity　and　low　biodegradability.　Therefore,　developing　a　reliable　method　to　simultaneously　detect　phenolic　pollutants　is　of　great　importance　to　environmental　safety　and　human　health.　Herein,　we　combined　the　advantages　of　metal　organic　frameworks　(MOFs)　and　covalent　organic　frameworks　(COFs)　to　prepare　two　cyclic　trinuclear　unit-based　metal　covalent　organic　framework　(MCOFs,　denoted　as　Cu3-TDH　COF　and　Cu3-BDU　COF)　with　large　specific　surface　area,　good　stability　and　excellent　laccase-like　activity.　Their　oxidative　degradation　ability　toward　phenolic　pollutants　was　verified,　and　a　dual-channel　nanozyme　sensor　array　based　on　Cu3-TDH　COF　and　Cu3-BDU　COF　was　constructed　for　the　identification　of　six　phenolic　pollutants.　Notably,　the　sensor　array　can　accurately　distinguish　between　different　concentrations　of　phenolic　pollutants　and　different　types　of　phenolic　pollutants　at　the　same　concentration,　even　at　levels　as　low　as　1　μM.　Moreover,　three　real　water　samples　(rainwater,　tap　water　and　wastewater)　and　18　unknown　samples　were　also　distinguished　and　differentiated　by　the　sensor　array.　This　study　opens　up　a　potential　avenue　for　the　design　of　MCOFs-based　nanozyme　sensor　arrays　to　simultaneously　realize　identification　and　detection　of　multiple　phenolic　pollutants.　©　2025　Elsevier　B.V.
