Nanoparticle organic hybrid materials (NOHMs) are liquid-like materials composed of an inorganic core to which a polymeric canopy is ionically tethered. NOHMs have unique properties including negligible vapor pressure, high oxidative thermal stability, and the ability to bind to reactive species of interest due to the tunability of their polymeric...

The development of effective catalysts is one of the big challenges associated with a new circular carbon economy addressing climate change.

Herein we describe the use of a metal-organic framework (MOF) with a composition of [Ni3(pzdc)2(ade)2(H2O)1.5](H2O)1.3, for the selective capture of carbon dioxide (CO2) from wet flue gas followed by its...

Single-species light emitters with high photoluminescence quantum yields (PLQYs) and broad- spectrum color tunability are sought-after for applications ranging from bio-imaging to artificial lighting. We explore a new strategy to design such emitters, inspired by bioluminescent fireflies and click-beetles. These organisms use a single molecular sub...

The threat posed by the presence of artificial volatile organic compounds (VOCs) in the environment is a widely acknowledged fact, both for environmental issues and human health concerns. Ever-increasing production requires the continuous development of technologies toward the removal of these substances. In recent years, metal-organic frameworks (...

A strategy based on the use of ligand steric hindrance and metal doping is reported for the design and synthesis of near-infrared (NIR) emitting lanthanide-based metal-organic frameworks (MOFs). The lanthanide...

Metal organic frameworks (MOFs) are increasingly used in applications that rely on the optical and electronic properties of these materials. These applications require a fundamental understanding on how the structure of these materials, and in particular the electronic interactions of the metal node and organic linker, determines these properties....

Flexible and transformable molecules, particularly those responding to external stimuli, are needed for designing sensors and porous compounds capable of storing or separating gases and liquids. Under normal conditions the photochromic compound, 1,2-bis[2-methyl-5-(pyridyl)-3thienyl]cyclopentene (BTCP) forms a porous co-crystal with 1,4-diiodotetra...

Limiting the increase of CO2 in the atmosphere is one of the largest challenges of our generation¹. Because carbon capture and storage is one of the few viable technologies that can mitigate current CO2 emissions², much effort is focused on developing solid adsorbents that can efficiently capture CO2 from flue gases emitted from anthropogenic sourc...

A lanthanide-based metal–organic framework (MOF), named SION-2, displays strong and tuneable uniaxial negative thermal expansion (NTE). The coefficient of thermal expansion α1 reaches –153(6) MK–1 between 100 and 340 K, which is among the highest values reported to date for Ln-based MOFs. After heating to 380 K and subsequent cooling, the direction...

Compounds exhibiting tuneable fluorescence emission upon heating or cooling are considered smart materials as their optical properties can be exquisitely controlled by adjusting the external temperature. Herein, we report such a material, which is a porous pyrene-based metal–organic framework with a chemical formula of [Mg1.5(HTBAPy)(H2O)2]·3DMF (H...

Biologically derived metal-organic frameworks (bio-MOFs) are of great importance as they can be used as models for bio-mimicking and in catalysis, allowing us to gain insights into how large biological molecules function. Through rational design, here we report the synthesis of a novel bio-MOF featuring unobstructed Watson-Crick faces of adenine (A...

Sustainable catalysts based on earth-abundant elements are considered as economical alternatives to precious-metal-bearing catalysts and could be impactful for many applications. Self-healing sustainable catalysts, which in addition to their ‘green’ characteristic can spontaneously repair themselves without the need of applying heat, pressure or el...

Prolonged consumption of water contaminated with fluoride ions (F–) at concentrations exceeding 1.5 ppm can lead to considerable health implications, particularly in children and developing embryos. With irreversible and potentially severe forms of fluoride (F–) toxicity such as skeletal fluorosis being endemic in at least 25 countries, constructin...

In this work, we report the synthesis of SION-8, a novel metal–organic framework (MOF) based on Ca(II) and a tetracarboxylate ligand TBAPy4– endowed with two chemically distinct types of pores characterised by their hydrophobic and hydrophilic properties. By altering the activation conditions, we gained access to two bulk materials: the fully activ...

We report here two isoreticular ytterbium (Yb) 2D metal-organic frameworks (MOFs) emitting near-infrared (NIR) luminescence with 1.26(2)% quantum yield values, which are among the highest values reported to date for MOFs incorporating NIR-emitting lanthanide cations. The excitation wavelength of the YbIII MOFs can be red-shifted to the visible rang...

We report the syntheses and structures of five metal-organic frameworks (MOFs) based on transition metals (NiII, CuII, and ZnII), adenine, and di-, tri-, and tetra-carboxylate ligands. Adenine, with multiple N donor sites, was found to coordinate to the metal centers in different binding modes including bidentate (through N7 and N9, or N3 and N9) a...

Recyclable materials for simultaneous detection and uptake of ammonia (NH3) are of great interest due to the hazardous nature of NH3. The structural versatility and porous nature of metalorganic frameworks (MOFs) make them ideal candidates for NH3 capture. Herein, we report the synthesis of a water-stable and porous 3-dimensional Cu(II)-based MOF (...

Understanding how crystalline materials are assembled is important for the rational design of metal organic frameworks (MOFs), through streamlining their synthesis and controlling their properties for targeted applications. Herein, we report for the first time the construction of two 3-dimensional Tb(III) based MOFs; a metastable MOF acting as an i...

We present the in silico design of a MOF-74 analog, hereon known as M2(DHFUMA) [M = Mg, Fe, Co, Ni, Zn], with enhanced small molecule adsorption properties over the original M2(DOBDC) series. Constructed from 2,3-dihydroxyfumarate (DHFUMA), an aliphatic ligand which is smaller than the aromatic 2,5-dioxidobenzene-1,4-dicarboxylate (DOBDC), the M2(D...

The crystal structure of arsenolite, the cubic polymorph of molecular arsenic(III) oxide, has been determined by single-crystal X-ray diffraction up to 30 GPa. The bulk of the crystal is monotonically compressed with no detectable anomalies to 60% of the initial volume at 30 GPa. The experimental As4O6 crystal compression exceeds that obtained by v...

A soft porous material [Zn(L)2(OH)2]n∙Guest (where L is 4-(1H-naphtho[2,3-d]imidazol-1-yl)benzoate, and Guest is water or methanol), exhibits the strongest ever observed negative area compressibility (NAC), an extremely rare property, as at hydrostatic pressure most materials shrink in all directions and few expand in one direction. This is the fir...
