Overview

Experimental study demonstrates aggregation-regulated multi-mode phosphorescence in single-component cellulose trimellitate, indicating potential for eco-friendly anticounterfeiting inks.

Key Points

  • To develop single-component, environmentally friendly room-temperature phosphorescent materials capable of multi-mode emission, tunable excitation-dependence, and visible-light activation through aggregation engineering.
  • Synthesized single-component anionic cellulose trimellitate derivatives, including CBtCOONa, from renewable cellulose.
  • Controlled the molecular aggregation state to produce molecularly dispersed, fully aggregated, and coexisting chain-aggregate forms.
  • Characterized emission wavelengths and afterglow profiles under ultraviolet and visible-light excitation, followed by trial printing of anticounterfeiting codes.
  • Molecularly dispersed CBtCOONa produced blue phosphorescence, whereas fully aggregated states emitted green phosphorescence and responded directly to visible-light activation.
  • Coexistence of dispersed single chains and aggregates generated excitation-dependent, color-tunable phosphorescence.
  • Water-processable cellulose formulations functioned effectively as security inks to print complex, disposable anticounterfeiting patterns and information codes.
