Aggregation-induced　emission　(AIE)　based　luminescent　materials　are　generating　intensive　interest　due　to　their　unique　fluorescence　in　the　aggregation　state.　Herein　we　report　a　strategy　of　dynamic　covalent　chemistry　(DCC)　controlled　AIE　luminogens　for　the　regulation　of　multicolor　emission　in　reversible　covalent　polymer　networks.　Tetraphenylethene　derived　ring-chain　tautomers　were　prepared,　and　the　emission　was　readily　controlled　through　multimode,　such　as　changing　the　solvent,　adding　the　base,　and　dynamic　covalent　reactions　with　amines.　Moreover,　the　construction　of　dynamic　covalent　cross-linked　luminescent　hydrogels　with　tunable　fluorescent,　self-healing,　and　mechanical　properties,　was　realized.　The　combination　of　AIE　and　aggregation-caused　quenching　(ACQ)　fluorophores　in　the　polymer　network　further　enabled　the　realization　of　a　multicolor　modulator,　including　white　emission,　in　both　solution　and　gel　states.　The　strategies　and　results　presented　should　find　utility　in　dynamic　assemblies,　polymer　networks,　chemical　sensing,　and　responsive　materials.　(C)　2022　Published　by　Elsevier　B.V.　on　behalf　of　Chinese　Chemical　Society　and　Institute　of　Materia　Medica,　Chinese　Academy　of　Medical　Sciences.
