Defect engineering in metal-organic frameworks (MOFs) is an exciting concept for tailoring material properties, which opens up novel opportunities not only in sorption and catalysis, but also in controlling more challenging physical characteristics such as band gap as well as magnetic and electrical/conductive properties. It is challenging to structurally characterize the inherent or intentiona...

Synthesized new Al and Zr-MOFs with bipyridine • links for isoreticluar metallation. Developed aziridation reactions to introduce • ethanediamine group (-NHCH2CH2NH2) on newly prepared MOFs with amino groups. Began metal-doping experiments for immobilization • of metal complexes. Environment of the metal coordination sites was • studied by the extended X-ray absorption fine structure spectrosco...

Tuna, billfish, and oceanic sharks [hereafter referred to as 'mobile oceanic fishes and sharks' (MOFS)] are characterised by conservative life-history strategies and highly migratory behaviour across large, transnational ranges. Intense exploitation over the past 65 years by a rapidly expanding high-seas fishing fleet has left many populations depleted, with consequences at the ecosystem level ...

Metal–organic frameworks (MOFs) usually have micropores smaller than 2 nm, which may restrict their applications in some cases. Hierarchical-pore MOFs (H-MOFs) are a new family of MOF materials, possessing both microand mesopores to address this problem. Here we demonstrate a competitive coordination strategy for the synthesis of H-MOF nanostructures, such as two-dimensional (2D) H-MOF nanoshee...

Owing to their outstanding structural, chemical, and functional diversity, metal-organic frameworks (MOFs) have attracted considerable attention over the last two decades in a variety of energy-related applications. Notably missing among these, until recently, were applications that required good charge transport coexisting with porosity and high surface area. Although most MOFs are electrical ...

Three new solvent-induced metal-organic frameworks (MOFs)-[Cd(H2L)(H2O)3]·NMP (), [Cd3(L)(H2O)4(OH)2] () and [Cd(L)0.5(H2O)]·H2O ()-were designed and successfully prepared via solvothermal reaction by multidentate phenyltetracarboxylic acid [1,1':4',1''-terphenyl]-2',3,3'',5'-tetracarboxylic acid (H4L) and Cd(ii) salts in various solvent systems. Structural analyses indicated that the H2L/L lig...

Photocatalysts based on metal-organic frameworks (MOFs) are very promising due to a combination of high tuneability and convenient porous structure. Introducing porphyrin units within MOFs is a potential route to engineer these natural photosynthesis molecular catalysts into artificial photosynthesis heterogeneous catalysts. Using computer simulations based on density functional theory, we expl...

Nature Materials 14, 924–930 (2015); published online 3 August 2015; retracted after print 24 November 2016. We wish to retract this Article due to concerns with some data related to upconversion in the solid-state samples presented in Fig. 4d,e, and to the reproducibility check of the triplet diffusion constant provided in the Supplementary Information. In this Article, we reported fast triple...

BACKGROUND Granulosa cells play a key role in folliculogenesis and female reproduction. Our previous study demonstrated that water channel aquaporin-8 (AQP8) is expressed in mouse follicular granulosa cells and is an important determinant of granulosa cell apoptosis and follicular maturation. More roles of AQP8 in folliculogenesis remain to be determined. FINDINGS The present study reports th...

The synthesis and characterization of an isomorphous series of copper-containing microporous metal-organic frameworks (MOFs) based on triazolyl isophthalate linkers with the general formula [Cu₄(μ₃-OH)₂(R¹-R²-trz-ia)₃(H₂O)x] are presented. Through size adjustment of the alkyl substituents R¹ and/or R² at the linker, the impact of linker functionalization on structure-property relationships was ...
