Synthesis, structures and Cr 2 O 7 2− fluorescence sensing properties of novel Zn( ii )/Cd( ii ) metal–organic frameworks with diverse N/O-donor ligands

Four novel Zn( ii )/Cd( ii ) MOFs were synthesized and characterized. Luminescence studies revealed that these MOFs exhibited high sensitivity and selectivity in fluorescence sensing for Cr 2 O 7 2− with detection limits of 3.64, 2.08, 2.75 and 4.36 μM.
