A highly thermal and pH-stable fluorescence sensor for rapid detection of Hg²⁺, Fe³⁺, and tetracycline in aqueous solutions

Abstract

Under solvothermal conditions, one new CdⅡ coordination polymer [Cd(bbimc)(ata)]n (1)] based on carbazole ligand 3,6-bis (1H-benzo[d]imidazol-1-yl)-9-methyl-9H-carbazole (bbimc) and 2-aminoterephthalic acid ligand (H2ata) was synthesized. Single-crystal structural determination reveals that 1...

Highly selective and sensitive fluorescent probes for nitrofurazone and Hg2+ by two Zn (II)‐based coordination polymers

“…33 Similarly, Sun et al, the group reported carbazole-based rigid ligand toward fluorescence sensor for rapid detection of Hg 2+ , Fe 3+ , and tetracycline in aqueous solutions. 34 Advancements in the application of coordination polymers (CPs), which are hybrid organic/inorganic porous materials, are being made in the sensory detection field. 35 Due to various parameters like unique topology, conformational rigidity, structural tunability, and intrinsic cavity voids, CPs exhibit great selectivity toward certain analytes based on their size, shape, and functionality.…”
