“…The introduction of monotopic ligands was proposed by the groups of Kitagawa and Behrens41,42 to modulate the size and shape of the crystallites of MOFs through competition of complexation with the polytopic ligands. More precisely, in the case of polycarboxylate Zr MOFs, the addition of a very large excess of monocarboxylic acid typically leads to an increase in the size of the crystallites, hence facilitating the structure determination,7,41,43–50 although potentially leading to local defects 51,52. We therefore explored the effect of the addition of co‐ligands of various strengths [benzoic acid, terephthalic acid (H 2 bdc), salicylic acid (H 2 sal), catechol and pyrogallol] on the reaction mixture.…”

Zr^IV Coordination Polymers Based on a Naturally Occurring Phenolic Derivative

The reactivity under solvothermal conditions of the ZrIV ion with the naturally occurring gallic acid ligand has been evaluated in depth. The study led to the isolation of four microcrystalline hydroxycarboxylate‐based coordination polymers (MIL‐151 to ‐154). Through the use of a combination of solid‐state NMR and high‐resolution X‐ray powder diffraction analyses, the structures of two of these phases (MIL‐153, MIL‐154) were solved. In both cases, the gallol motifs favour the formation of rod‐like inorganic units built up from ZrO8 polyhedra. Although one compound (MIL‐151) was found to be microporous (SBET ≈ 470 m2 g–1), its poor crystallinity prevented comprehensive structural analysis. Nevertheless, a comparison of its physicochemical features with those of the fully characterized solids allows a plausible structural model to be proposed.

“…Lin et al reported that phosphorescent Ir and Ru complexes decorated with two carboxylate groups can be doped into the framework of a remarkably stable MOF [Zr 6 O 4 (OH) 4 (bpdc) 6 ] (UiO-67) to achieve high oxygen sensitivity with much reduced use of precious metal ( Figure 14 ). [ 127 ] UiO-67 consists of 12-connected Zr 6 O 4 (OH) 4 clusters linking by bpdc 2− ligands into an fcu topology network. The M(ppy) x (22bpy) 3− x (M = Ir(III) or Ru(II), x = 1, 2, 3) derived linear dicarboxylate ligands were used to partially (0.48-2.98%) replace the bpdc 2− ligands in UiO-67.…”

Photoluminescent Metal–Organic Frameworks for Gas Sensing

et al. 2016

Luminescence of porous coordination polymers (PCPs) or metal–organic frameworks (MOFs) is sensitive to the type and concentration of chemical species in the surrounding environment, because these materials combine the advantages of the highly regular porous structures and various luminescence mechanisms, as well as diversified host‐guest interactions. In the past few years, luminescent MOFs have attracted more and more attention for chemical sensing of gas‐phase analytes, including common gases and vapors of solids/liquids. While liquid‐phase and gas‐phase luminescence sensing by MOFs share similar mechanisms such as host‐guest electron and/or energy transfer, exiplex formation, and guest‐perturbing of excited‐state energy level and radiation pathways, via various types of host‐guest interactions, gas‐phase sensing has its unique advantages and challenges, such as easy utilization of encapsulated guest luminophores and difficulty for accurate measurement of the intensity change. This review summarizes recent progresses by using luminescent MOFs as reusable sensing materials for detection of gases and vapors of solids/liquids especially for O2, highlighting various strategies for improving the sensitivity, selectivity, stability, and accuracy, reducing the materials cost, and developing related devices.

This review explores the structures and properties of UiO‐67 and its derivatives as well as the corresponding synthetic and characterization method. With remarkably high surface area, high thermal and chemical stabilities and excellent mechanical properties, UiO‐67 is very promising and competitive among kinds of metal‐organic frameworks. UiO‐67 not only has good performance on some gases adsorption and storage and removal of organophosphorus pesticides, but also can act as the catalyst in the nerve‐agent hydrolysis. More importantly, by introducing various functional organic linkers into UiO‐67 framework or incorporating different metal complexes and other functional groups, the resulting derivatives of UiO‐67 can improve its water stability, show enhanced gases adsorption properties and expand the application of UiO‐67 such as catalytic hydrolysis of phosphate‐ester, catalytic detoxication of chemical warfare agents, catalytic promotion of Friedel–Crafts reactions, Suzuki–Miyaura cross‐coupling reaction, C−C and C−H bond activation reactions and a series of photocatalytic reactions, catalytic addition of asymmetric aldol, micromotor engines, detection of some biological thiols and so on.
