“…Neither is significantly changed at subsequent time points. Both the PXRD and the morphology of water-exposed crystals closely resemble a layered ZIF reported elsewhere, synthesized from zinc and 6-(methylmercapto)purine. The resemblance suggests that ZIF-20 NPs undergo a phase transformation into 2D sheets, and then delaminate to form the platelike NPs observed after water exposure.…”

Owing to their facile synthesis, tailorable porosity, diverse compositions, and low toxicity, zeolitic imidazolate framework (ZIF) nanoparticles (NPs) have emerged as attractive platforms for a variety of biologically relevant applications. To date, a small subset of ZIFs representing only two topologies and very few linker chemistries have been studied in this realm. We seek to expand the bio-design space for ZIF NPs through the targeted synthesis of a hierarchically complex ZIF based on two types of cages, ZIF-20, with lta topology. This study demonstrates the rapid synthesis and size tunability of ZIF-20 particles across the micro and nanoregimes via microwave heating and the use of a modulating agent. To evaluate the utility of ZIF particles for biological applications, we examine their stability in biologically relevant media and demonstrate biocompatibility with A549 human epithelial cells. Further, the ability to encapsulate and release methylene blue, a therapeutic and bioimaging agent, is validated. Importantly, ZIF-20 NPs display a unique behavior relative to previously studied ZIFs based on their specific structural and chemical features. This finding highlights the need to expand the design space across the broader ZIFs family, to exploit a wider range of relevant properties for biological applications and beyond.

“…The carbonyl peak of the guest solvent arises at 1683 cm –1 for 1 , 1653 cm –1 for 2 , 1615 cm –1 for 3 , and 1680 cm –1 for 4 (Figures S8 and S9). Thermogravimetric analyses of 1 – 4 display (Figures S10 and S11) an initial weight loss up to 150 °C, probably due to the expulsion of included solvent molecules. The plateaus ranging from 150–290 °C indicate thermally stable frameworks.…”

Astute combination of basic functionality and luminescence property can pursue multifunctional metal−organic frameworks (MOFs) with assorted applications such as selective CO 2 adsorption, specific detection of explosive nitro compounds, and toxic metal ion sensing. The bifunctional ligand 4-(4-carboxyphenyl)-1,2,4-triazole (HL) is used to build the framework [Cd(L) 2 ]•(DMF) 0.92 (1) (L = L −1 , DMF = N,N′-dimethylformamide), having a free N atom decorated porous channel. The solvothermal synthesis is extended to produce three isoskeletal frameworks in diverse solvents, where pore size maximizes in 2 by employing N,N′-diethylformamide solvent. The activated framework [Cd(L) 2 ] exhibits strong CO 2 affinity with good CO 2 /N 2 selectivity, and shows minimum CO 2 loss during five adsorption−desorption cycles. Sensing studies for nitro-aromatic compounds in DMF reveal highly specific detection of 2,4,6-trinitophenol (TNP) with remarkable quenching (K SV = 9.3 × 10 4 M −1 ) and low limit of detection (LOD: 0.3 ppm). The quenching mechanism is ascribed to the combined existence of static and dynamic quenching plus resonance energy transfer. The activated framework further shows highly selective luminescent detection of Cu 2+ ions with a quenching constant of 4.4 × 10 3 M −1 and very low LOD of 3.9 ppm. The detection of Cu 2+ ions accompanies a visible color change in solution and solid phase, which validates the present system as a potential colorimetric Cu 2+ sensor. Of note is that bifunctional sensor shows excellent reusability toward TNP and Cu 2+ detection. Overall, selective and multicycle CO 2 adsorption, together with efficient sensing of both TNP and Cu 2+ ion, manifest this pore-functionalized MOF as a versatile material for sustainability.

“…Cu I is coordinated by two 1-(N 9 -adenine)-3,6-dithiaheptane ligands via four S atoms to form a complex that contains two adenine residues (Galindo et al, 2009b). Recently, a Zn complex with 6-MMP (6-methylmercaptopurine) was prepared by Perea-Cachero et al (2016); it is a two-dimensional polymer with the Zn atoms acting as bridges between the ligands via N atoms at the N9 and N7 positions.…”

Silver nitrate reacts with 6-methylmercaptopurine riboside (6-MMPR) in aqueous solution containing methanol and dimethyl sulfoxide at room temperature to give a colourless crystalline complex, namely, bis(6-methylmercaptopurine riboside-κN 7)(nitrato-κ2 O,O′)silver(I) 2.32-hydrate, [Ag(NO3)(C11H14N4O4S)2]·2.32H2O. The crystal structure, determined from synchrotron diffraction data, shows a central AgI ion on a crystallographic twofold rotation axis, coordinated in an almost linear fashion by two 6-MMPR ligands via atom N7 (purine numbering), with the nitrate counter-ion loosely coordinated as a bidentate ligand, forming a discrete molecular complex as an approximate dihydrate. The complex and water molecules are connected in a three-dimensional network by hydrogen bonding.

Synthesis, structure and characterization of a layered coordination polymer based on Zn(ii) and 6-(methylmercapto)purine

Abstract: A layered coordination polymer was synthesized from Zn(ii) and 6-(methylmercapto)purine (mMP-H) in N,N-dimethylformamide (DMF). Its structure and formula [Zn2(μ2-mMP)3(NO3)(DMF)(H2O)]n·nDMF were determined by single crystal X-ray diffraction.
