Abstract: 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 active pharmaceutical agents, cosmetically interesting compounds and markers. Apart from the intrinsic properties thereof for imaging, said nanoparticles give good results in terms of capacity of loading with medicaments and in biocompatibility.

Abstract: A process for preparing a porous solid with an outer surface modified by at least one polymer; the polymer being simultaneously synthetized in solution and grafted on the outer surface of the solid, includes contacting: a porous solid; and a polymer-precursor solution comprising an adhesion primer, and at least one polymerizable monomer; under conditions enabling the formation of radical entities.

Abstract: The present invention concerns metal-organic hybrid solids having a modified outer surface. These solids can be used, for example, for the storage and vectoring of molecules of interest such as pharmaceutically active ingredients, compounds of interest in cosmetics and markers, for example contrast agents. These solids have good results in terms of active drug loading capacities, biocompatibility, stability and controlling the release of the active ingredients encapsulated.

Abstract: 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.

Abstract: The present invention relates to the use of solids consisting of a metal-organic framework (MOF) and having the units of the following formula (I): MmOkXILp as a nitrogen-oxide catalyst. The present invention also relates to devices for enabling the implementation of said use. The nitrogen oxides in question are nitrogen monoxide and nitrogen dioxide, collectively referred to as NOx. The MOF solids of the present invention are advantageously capable of removing nitrogen oxides from a liquid or gaseous effluent, for example from water, from the exhaust gases of a vehicle, factory, workshop, laboratory, stored products, urban air vents, etc., without any reducing agent and at a low temperature. The DeNOx catalysis is a major issue for our societies. The invention can be used for reducing or even avoiding the consequences for public health of the toxic NOx gases resulting from human activity.
