Taking lanthanides out of isolation: tuning the optical properties of metal-organic frameworks

Kevin Sivula, Gloria Capano, Muhammad Aiman Bin Rahmanudin Hamdan, Nestor Guijarro Carratala, Berend Smit, Samantha Lynn Anderson, Kyriakos Stylianou, Davide Tiana, Andrzej Gladysiak, Christopher Patrick Ireland, Stavroula Kampouri, Maria Fumanal Quintana

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 t ...

Rapid, Selective Heavy Metal Removal from Water by a Metal-Organic Framework/Polydopamine Composite

Emad Oveisi, Seyedmohamad Moosavi, Daniel Teav Sun, Wendy Lee Queen, Davide Tiana, Li Peng

Drinking water contamination with heavy metals, particularly lead, is a persistent problem worldwide with grave public health consequences. Existing purification methods often cannot address this problem quickly and economically. Here we report a cheap, wa ...

Mixed-linker UiO-66: structure-property relationships revealed by a combination of high-resolution powder X-ray diffraction and density functional theory calculations

Berend Smit, Davide Tiana, Nicola Casati

The use of mixed-linker metal-organic frameworks (MIXMOFs) is one of the most effective strategies to modulate the physical-chemical properties of MOFs without affecting the overall crystal structure. In many instances, MIXMOFs have been recognized as soli ...

Adsorbate-induced lattice deformation in IRMOF-74 series

Berend Smit, Davide Tiana, Sudabeh Jawahery, Matthew David Witman, Efrem Daniel Braun, Cory Matthew Simon

IRMOF-74 analogues are among the most widely studied metal-organic frameworks ( MOFs) for adsorption applications because of their one-dimensional channels and high metal density. Most studies involving the IRMOF-74 series assume that the crystal lattice i ...

Metal-Organic Frameworks Invert Molecular Reactivity: Lewis Acidic Phosphonium Zwitterions Catalyze the Aldol-Tishchenko Reaction

Gerald Bauer, Berend Smit, Daniele Ongari, Davide Tiana, Xiangru Xu

The influence of metal-organic frameworks (MOFs) as additives is herein described for the reaction of n-alkyl aldehydes in the presence of methylvinylketone and triphenylphosphine. In the absence of a MOF, the expected Morita-Baylis-Hillman product, a beta ...

Origin of the Strong Interaction between Polar Molecules and Copper(II) Paddle-Wheels in Metal Organic Frameworks

Berend Smit, Daniele Ongari, Davide Tiana

The copper paddle-wheel is the building unit of many metal organic frameworks. Because of the ability of the copper cations to attract polar molecules, copper paddle-wheels are promising for carbon dioxide adsorption and separation. They have therefore bee ...

A universal chemical potential for sulfur vapours

Davide Tiana

The unusual chemistry of sulfur is illustrated by the tendency for catenation. Sulfur forms a range of open and closed S-n species in the gas phase, which has led to speculation on the composition of sulfur vapours as a function of temperature and pressure ...
