This work demonstrates AIE functionality in 3D polymers for selective barium ion detection, suggesting advances in environmental monitoring.
This study develops aggregation‐induced emission (AIE)‐active multilayer 3D polymers for selective barium ion (Ba 2+ ) detection. Synthesized from tailored monomers, these polymers overcome limitations of traditional fluorophores by emitting strongly in the aggregated state, enhancing environmental sensing. Rigorous testing confirms exceptional Ba 2+ selectivity and discrimination against interferents in water. This positions AIE‐based 3D polymers as promising tools for environmental monitoring, paving the way for advanced polymer sensor technologies to address critical environmental challenges.
