The development of advanced security materials with multimodal optical responses is of increasing relevance for anticounterfeiting technologies. In this study, we report the successful synthesis and comprehensive characterization of a multifunctional composite based on cellulose nanofibrils (CNFs) covalently functionalized with photochromic PSPA oligomers and cross-linked with upconversion nanoparticles (UCNPs).
