A bifunctional luminescent coordination polymer as recyclable sensor for detecting TNP and Fe3+ with high selectivity and sensitivity

A new Cd(II)-MOFs were synthesized and structurally characterized. Complex 1 is promising bifunctional luminescent probe for highly selective and sensitive sensing TNP and Fe3+ ions through luminescence quenching effect, the Ksv are up to 1.03 × 105 and 1.84 × 105 M−1. The complex also exhibits good recyclability for detecting TNP. The quenching mechanisms were studied based on both experiments and calculation.
