Abstract

A two-dimensional (2D) water-stable Cd (II) luminescent coordination polymer (1), namely {[CdLCl2]}n, was obtained through assembly of a new 2-deoxy-d-ribose derivative ligand (L) with CdCl2, 1 showed high stability in water. Further investigation showed that 1 can be used as luminescent probe for the organoarsenic compound Roxarsine (ROX) with high selectivity and sensitivity, high quenching constants (KSV = 2.34 × 104 M−1), low limits of detection (LOD) (0.16 μM) and good recyclability in aqueous media. In addition, this luminescent probe can detect some inorganic harmful ions (Fe3+, Cr2O72− and CrO42−) with excellent versatility. The detection mechanism was proved that the quenching was caused by competitive absorption and resonance energy transfer effect between 1 and analytes. More strikingly, a simple 1-based test strip was developed owing to the quick response and recyclability of 1, which shows visible quenching signals under UV light even when analytes concentrations are as low as 5 μM. This work has provided an effective method for the design of multifunctional CP luminescent sensors for pollutants detections in aqueous media.
