Different metal ions and anions are crucial for the life of organisms, but their excessive intake or deficiency cause various physiological abnormalities or diseases. Toxic metal ions such as Hg2+, Cr6+, Cd2+, explosive nitroaromatic compounds, and volatile organic compounds are widely used in agriculture, rocket fuels, and industry, but they cause severe effects on human health and environmental change. Hence, sensing and identification of these analytes are important for life, health, and environment protection. Recently, metal-organic frameworks (MOFs) have been extensively explored as luminescent sensors due to their unique crystallinity, structural diversity, tunable porosity, and functional groups. This chapter reviewed the origin of luminescent of MOFs and its applications as luminescent sensors for detecting different environmentally toxic analytes such as metal ions, anions, nitroexplosives, and volatile organic compounds. In addition, the detection mechanism of MOFs and its structural dependent properties are also illustrated.

A family of Cu(II)-based metal–organic frameworks (MOFs) has been synthesized using three pyridyl-isophthalate ligands, H 2 L 1 (4′-(pyridin-4-yl)biphenyl-3,5-dicarboxylic acid), H 2 L 2 (4′′-(pyridin-4-yl)-1,1′:4′,1′′-terphenyl-3,5-dicarboxylic acid) and H 2 L 3 (5-[4-(pyridin-4-yl)naphthalen-1-yl]benzene-1,3-dicarboxylic acid). Although in each case the pyridyl-isophthalate ligands adopt the same pseudo-octahedral [Cu 2 (O 2 CR) 4 N 2 ] paddlewheel coordination modes, the resulting frameworks are structurally diverse, particularly in the case of the complex of Cu(II) with H 2 L 3 , which leads to three distinct supramolecular isomers, each derived from Kagomé and square nets. In contrast to [Cu(L 2 )] and the isomers of [Cu(L 3 )], [Cu(L 1 )] exhibits permanent porosity. Thus, the gas adsorption properties of [Cu(L 1 )] were investigated with N 2 , CO 2 and H 2 , and the material exhibits an isosteric heat of adsorption competitive with leading MOF sorbents for CO 2 . [Cu(L 1 )] displays high H 2 adsorption, with the density in the pores approaching that of liquid H 2 . This article is part of the themed issue ‘Coordination polymers and metal–organic frameworks: materials by design’.

A series of structurally diverse coordination polymers, [Mn(ppmdc)(H2O)2]n (1), [Cu(ppmdc)(H2O)2]n (2), {[Co(ppmdc)][Co(ppmdc)(H2O)]}n (3), [Zn(ppmdc)(H2O)]n (4), and [Cd(ppmdc)]n (5) (H2ppmdc = 2-(pyridin-3-yl)-4,6-pyrimidine dicarboxylic acid) were obtained from metal salts and H2ppmdc under hydrothermal conditions. Single crystal X-ray structural analysis reveals that complexes 1–5 have different structures, ranging from one- to three-dimensions, which are mainly due to the different metal ions, and especially the coordination mode of the H2ppmdc ligand. Complexes 1 and 2 are 1D coordination polymers, in which the ppmdc2– ligand adopts a bis-(bidentate) mode to link metal ions. Complexes 3 and 4 feature a 2D metal-organic framework with Schläfli topologies of (4.62) (42.62.82) and (4.82), respectively, in which the metal ions are bridged by μ3-ppmdc2– ligands. Complex 5 possesses a 3D nanotubular metal-organic framework with a point symbol of (49.66) topology built up from the 6-connected ppmdc2– ligands and Cd(ii) ions. The thermal properties of complexes 1–5 have been determined. Moreover, investigation of photoluminescent properties reveals that the configuration of ppmdc2– resulting from metal-directed coordination has a profound effect on the fluorescence emissions of complexes 4 and 5.
