This challenge is addressed by employing cellulose nanocrystals (CNC), specifically carboxylated CNC, as a cholesteric host and coronene tetracarboxylate (CS) as a phosphorescent guest. The self\u2010assembled CNC matrix provides a rigid, anisotropic microenvironment through nanorod ordering and hydrogen bonding with CS, effectively suppressing non\u2010radiative relaxation. Systematic CS loading (0.3\u20135 wt%) reveals optimal performance at 1 wt% (lifetime: 1.756 s, quantum yield: 9.4%, 8 s afterglow), while higher loadings disrupt ordering and induce aggregation quenching. Three application strategies are further demonstrated: doping\u2010contrast Morse coding, water\/thermal rewritable patterns, and Rhodamine B\u2010mediated multicolor time\u2010sequenced luminescence. Collectively, these results show that CNC cholesteric order actively enhances RTP, establishing these biocomposite films as viable materials for advanced anti\u2010counterfeiting and encryption systems.<\/jats:p>","DOI":"10.1002\/chem.71808","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T04:22:52Z","timestamp":1792124572000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Long\u2010Afterglow Materials Enabled by the Confinement Effect of Cellulose Nanocrystals Cholesteric Liquid Crystals"],"prefix":"10.1002","author":[{"given":"Sichen","family":"Meng","sequence":"first","affiliation":[{"name":"School of Resources and Environmental Engineering Shanghai Polytechnic University  Shanghai P.
