| description | ABSTRACT Ultralong organic phosphorescence (UOP) materials have garnered significant interest for applications in advanced optical recording and information encryption. However, it remains a formidable challenge achieving manipulated phosphorescence due to the limited color channels and poorly populated triplet energy levels. Herein, we report a novel multiresponsive organic phosphorescence material, in which the phosphorescence color can be dynamically tuned with stimuli such as radiation duration, concentration, excitation wavelength, time, and temperature. The material is based on the confined 7H‐benzo[c]carbazole (BCz) molecules in the polymer matrix, which is achieved through the size‐dependent cluster‐triggered emission (CTE) mechanism. The BCz molecules form isolated molecules and different‐sized clusters in the matrix, resulting in multiple luminescent centers with different energy levels and phosphorescence lifetimes. Through matrix confinement effects, the activation states of the monomers and multiple clusters could be precisely modulated, resulting in temperature‐controlled tunable orange‐to‐green variations. Furthermore, the multiresponsive properties of the material have been used in both civil and military applications through sophisticated mathematical modeling. This work potentially proposes a guiding strategy for the development of multiresponsive UOP materials based on CTE molecules. |
