Recognition sites effects on turn off fluorescence detection of Fe3+

Two fluorescent Cd(II)-based metal-organic frameworks (MOFs), named [CdL(dpa)]·2.5H2O (1) and Cd2L2(2,2′-bpy)2 (2) (H2L = 5-[(dimethylamino)thioxomethoxy]-1,3-benzenedicarboxylic acid, dpa = 4,4′-dipyridylamine and 2,2′-bpy = 2,2′-bipyridine), were successfully exploited as fluorescent sensors for...
