Patent number: 11426704Abstract: The use of porous crystalline solids constituted of a metal-organic framework (MOF) for the capture of polar volatile organic compounds (VOCs). In particular, the MOF of interest are material having an average pores sizes of 0.4 to 0.6 nm and an hydrophobic core formed by a metal oxide and/or hydroxide network connected by linkers, the linkers being selected from the group including (i) C6-C24 aromatic polycarboxylate linkers, such as benzyl or naphtyl di-, tri- or tetracarboxylate, and (ii) C6-C16 polycarboxylate aliphatic linkers; the linkers bearing or not apolar fluorinated groups, e.g. —(CF2)n—CF3 groups, n being a integer from 0 to 5, preferably 0 ou 3, and/or apolar C1-C20 preferably C1-C4 alkyl groups, e.g. —CH3 or —CH2—CH3, grafted directly to the linkers and pointing within the pores of the MOF.Type: GrantFiled: September 12, 2018Date of Patent: August 30, 2022Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, ECOLE NORMALE SUPERIEURE DE PARIS, ECOLE SUPERIEURE DE PHYSIQUE ET DE CHIMIE INDUSTRIELLES DE LA VILLE DE PARIS, UNIVERSITÉ DE VERSAILLES—SAINT-QUENTIN-EN-YVELINES, INSTITUTO SUPERIOR TÉCNICOInventors: Christian Serre, Moisés L.

Patent number: 10065979Abstract: The invention relates to nanoparticles made from organometallic hybrid materials made from iron carboxylates, used for example as contrast agents. The particles can also be used for the encapsulation and vectoring of molecules of interest such as active3 pharmaceutical agents, cosmetically interesting compounds and markers. Apart from the intrinsic properties thereof for imaging, said nanoparticles give good results in terms of capacity for loading with medicaments and in biocompatibility.Type: GrantFiled: October 1, 2008Date of Patent: September 4, 2018Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE-CNRS, UNIVERSITÉ DE VERSAILLES—SAINT-QUENTIN-EN-YVELINESInventors: Patricia Horcajada-Cortes, Gérard Ferey, Christian Serre, Ruxandra Gref, Patrick Couvreur

Patent number: 8926736Abstract: The present invention relates to reducible porous crystalline solids, constituted of a metal-organic framework (MOF), for the separation of mixtures of molecules having different unsaturation degrees and/or a different number of unsaturations with a selectivity that can be adjusted by controlling the reduction of the MOF. The MOF solids of the present invention, after reduction, have a strong affinity for molecules containing at least one unsaturation. They can be used in various separation processes, especially those relating to hydrocarbons.Type: GrantFiled: June 11, 2009Date of Patent: January 6, 2015Assignees: Centre National de la Recherche Scientifique -CNRS-, Universite de Caen-Basse Normandie, Universite de Versailles—Saint Quentin en Yvelines, Korea Research Institute of Chemical & Technology (KRICT)Inventors: Christian Serre, Alexandre Vimont, Philip Llewellyn, Jong-San Chang, Patricia Horcajada-Cortes, Gérard Ferey, Marco Daturi, Young-Kyu Hwang
