Dual-responsive luminescent sensors based on two Cd-MOFs: rare enhancement toward acac and quenching toward CrO
Assembled from a reduced Schiff base tricarboxylate ligand H 3 L, two novel Cd-MOFs with the formulae {[Cd(HL)(bpy)]·1.25H 2 O·1.5DMF} n ( LCU-107 ) and {[Cd(HL)(bpea)·H 2 O]·H 2 O·DMF} n ( LCU-108 ) (where LCU stands for Liaocheng University, H 3 L = 5-(4-carboxybenzylamino)isophthalic acid, bpy =...
