Abstract:
Photocontrollable luminescent materials with highly efficient emission properties offer promising application prospects in the field of intelligent switches, information security, etc. Herein, two stimulus-responsive CPs (CPs 1-2) have been successfully synthesized based on the photoactive TPT ligand (2,4,6-tris-4-pyridyl-1,3,5-triazine) via the solvothermal method. Remarkably, CPs 1-2 exhibit distinct photochromism coupled with photocontrollable luminescence behaviors. Furthermore, by employing an in situ doping strategy, lanthanide ions were immobilized within the pores of CP 2 to generate Eu/Tb@CP 2 composites, which display significantly enhanced fluorescence (QY increased from 0.49% to 16.5%) without compromising photochromic properties. Moreover, leveraging their dynamic, efficient, and multicolor luminescence, these compounds enable the realization of multimode smart displays. This work offers valuable insights for designing novel stimulus-responsive materials with efficient and color-tunable luminescence via in situ doping strategies, thereby advancing the development of photochromic materials toward practical applications in multilevel information display and advanced data encryption.
