Abstract
Here firstly report a novel 3D bimetallic MOF. It can be used as a fast ratiometric fluorescent probe and fast adsorbent for Pb2+ ions with its greatly fluorescence enhancement and a large red-shift stokes of 166 nm, which is the biggest shift of references. Moreover, it is also the first reported MOF material that can quantitatively analyze the lanthanide metal element Tb3+ among LMOFs. The limits of detection are calculated as 4.12 × 10−6 M and 2.94 × 10−5 M. ICP-OES testing and calculation showed that the maximum adsorption capacity of LMOF-1 for Pb2+ was calculated to be 23.75 mg/g at five minutes.
