Two-dimensional luminescence metal organic framework nanosheets (LMOF) named NH2-CuMOFs were synthesized using Cu (II) nodes coordinated with negatively charged 2-aminoterephthalic acid (NH2-BDC) via a bottom-up strategy, which were first used as the fluorescent probes for the detection of chromium...
