|Abstract||Luminescent rare-earth (RE) complexes usually present outstanding advantages of long-lived emissions and high emission efficiency in aggregate and solid states. However, the combination of aggregation-induced emission (AIE)-based materials and RE complexes with excellent luminescent properties is rarely reported. Herein, AIE luminogens (AIEgens)-based Tb3+ complex (TPE-Tb) was designed and synthesized for the first time, which can self-assemble into novel TPE-Tb nanoparticles to be used as ratiometric fluorescent probe for sensitive and rapid detection of anthrax spore biomarker in aqueous solution or actual spores. The results indicated that the limit of detection (LOD) of this ratiometric fluorescent probe was as low as 0.187 nM and 1.64 × 104 spores/mL in water solution or actual spore samples, respectively. This work explored a new method for the combination of AIEgens-based materials and RE complexes by coordination mode and provided a versatile nanoprobe candidate for anthrax biomarker detection. © 2020|
