Construction of ZnII/CdII-CPs and their fluorescent detection for Fe3+, Cr2O72− and TNP in water via luminescence quenching

Two novel fluorescent coordination polymers with TiSc topology (CP 1) and a five-fold interpenetration framework (CP 3) exhibit a fluorescent turn-off sensing behavior for Fe 3+ , Cr 2 O 7 2− and TNP in aqueous solution with high selectivity and sensitivity.
