Abstract
luminescence upon heating. Such multifunctional optical behavior enables precise multicolor modulation and exceptional adaptability to complex external stimuli. Capitalizing on their robust multi-stimuli responsiveness, these materials were further applied in erasable photopatterning and sequential logic information encryption systems. This work offers a new design strategy for lanthanide metallopolymers and may contribute to the development of next-generation intelligent multifunctional materials.
