Very Large Swelling in Hybrid Frameworks: A Combined Computational and Powder Diffraction Study.
Using a combination of simulations and powder diffraction, we report here the study of the very large swelling of a three-dimensional nanoporous iron(lll) carboxylate (MIL-88) which exhibits almost a reversible doubling (∼85%) of its cell volume while fully retaining its open-framework topology. The...

The crystal structure of the open form of MIL-88 has been successfully refined and indicates that atomic displacements larger than 4 Å are observed when water or various alcohols are adsorbed in the porous structure, revealing an unusually flexible crystallized framework. X-ray thermodiffractometry shows that only a displacive transition occurs during the swelling phenomenon, ruling out any bond breaking. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2005 holdings: @attributes: islocal: N |
