“…8−10 Due to their highly porous and flexible structure, MOFs have been widely used as adsorbents to remove the organic pollutants in the liquid-phase separations for environmental cleaning/water purification. 11−15 Recently, tremendous efforts have been taken to improve the adsorption capacity and separation efficiency of organic pollutants by MOFs via different approaches. 16,17 For example, as for the adsorption capacity, many works have been focused on the adjustment of central metal ions and organic ligands to improve the pore size and increase the binding sites.…”

Three-dimensional carbon-based porous materials have proven to be quite useful for tailoring material properties in the energy conservation and environmental protection applications. In view of the three-dimensional and well-defined structure of metal–organic frameworks (MOFs), a novel carbon-based magnetic porous material (HKUST–Fe 3 O 4 ) has been designed and constructed by MOF–guest interactions of high-temperature pyrolysis. The obtained HKUST–Fe 3 O 4 exhibited the unique features of superparamagnetism, a macro/mesoporous structure, environmental protection (inexistence of toxic heavy metal ions), and physicochemical stability and has shown high adsorption capacity and rapid adsorption for carcinogenic organic pollutants (for example, rhodamine B) with an environmentally friendly character and excellent reusability. We demonstrate that the unique/superior advantages of HKUST–Fe 3 O 4 could meet the requirements of environment cleaning, especially for removing the targeted organic pollutant from water. Moreover, the specific HKUST–Fe 3 O 4 and organic pollutant interaction mechanism has been analyzed in detail via parameter-free calculations. This study proposes a promising strategy for constructing novel carbon-based magnetic nanomaterials for various applications, not limitated to pollutant removal.

A Zr-based metal–organic framework (Zr-MOF) which has free carbonyl groups is synthesized successfully through mix-ligand strategy. Subsequently, Tb 3+ is encapsulated into a Zr-MOF by postcoordinated modification. The Tb 3+ @Zr-MOF exhibits the characteristic emission of Tb 3+ because of efficient sensitization through antenna effects. The Tb 3+ @Zr-MOF is further developed as a novel “turn-on” fluorescent probe to detect fluoride ions in aqueous solution. The results show that Tb 3+ @Zr-MOF exhibits excellent selectivity, high stability, low detection limits, and good anti-interference for sensitizing fluoride ions. In addition, the possible sensing mechanism that the induced luminescence properties may be attributed to Lewis acid–base interactions is discussed.

“…[24] Ligand-based emission properties have also been reported for Sc-CPs based on 2,5-furandicarboxylate ligands [25] and amino-terephthalate, [26] respectively. Emission could be initiated in a MIL-53 type structure MOF by incorporation of emitting Eu 3+ ions [27] and in PCN-333(Sc) by incorporation of a BODIPY (boron-dipyrromethene) fluorophore by click reaction. [28] Driven by our recent interest in the systematic investigation of Sc-CPs, we have now systematically explored the use of the two luminescent linear linker molecules H 2 BPDC and H 2 BPyDC for the synthesis of Sc-CPs.…”

Two new scandium-containing coordination polymers, with the formulae {(CH 3) 2 NH 2 }[Sc(BPDC) 2 ] (1) and [Sc(OH) (BPyDC)] (2) were solvothermally synthesized by using the linear linker molecules biphenyl-4,4′-dicarboxylic acid (H 2 BPDC) and 2,2′-bipyridine-5,5′-dicarboxylic acid (H 2 BPyDC). Crystal structures were determined from single-crystal and powder Xray diffraction data, respectively. The crystal structures of 1 and 2 contain isolated ScO 6 or chains of trans corner-sharing ScO 6
