Three metal–organic frameworks (MOFs) [M₂(d-cam)₂(bimb)₂]ₙ·3.5nH₂O (M = Mn for 1, Co for 2) and [Cd₈(d-cam)₈(bimb)₄]ₙ (3) (d-H₂cam = d-camphor acid, bimb = 4,4′-bis(1-imidazolyl)biphenyl), solvothermally synthesized, exhibit structural diversity. The charming aspect of these frameworks is that compound 3 is the very first MOF-based sensor for quantitatively detecting three different types of analytes (metal ions, aromatic molecules, and pesticides). And also, both compounds 2 and 3 show rapid uptake and ready regeneration for methyl orange (MO) and can selectively bind MO over methylene blue (MB) with high MO/MB separation ratio.
