A luminescent coordination polymer for selective, sensitive, and recyclable sensing of nitrobenzene in aqueous solution

JLNU-1 with 1D zigzag chain has been synthesized by hydrothermal reaction. JLNU-1 displays distinct PL emissions in different solvents. Especially, the dispersed solution of JLNU-1 in aqueous solution exhibits strong fluorescence emission, which could be quenched by trace amounts of nitrobenzene at ppm level. JLNU-1 can be utilized as a fluorescent sensor for the detection of nitrobenzene with high selectivity, sensitivity, and recyclability.184
