Anion-induced two stable isostructural Cd(ii) LMOFs based on benzotriazole with the highly selective detection of Fe3+ ions

Two new LMOFs , [Cd 9 (BTA) 6 (5-tbuip) 6 O 2 ] n ( LMOF-1 ) and [Cd 3 (BTA) 2 (5-tbuip) 2 ] n ( LMOF-2 ), show strong luminescence, and LMOF-1 can detect Fe 3+ with a very large quenching coefficient, indicating its potential application in chemical sensors.
