Advanced Functional Materials, EarlyView.Clusterization‐triggered emission is realized in dilute aqueous solution by introducing imine linkages into cellulose‐based luminophores. Imine functionalization creates O/N‐rich, hydrogen‐bonded clustered microenvironments that stabilize emissive states and restrict molecular motions. Luminescence is tunable by amine type and multiplicity.
