The present invention relates to a process for preparing a porous metal organic framework comprising at least two organic compounds coordinated to at least one metal ion, which comprises the steps (a) oxidation of at least one anode containing metal corresponding to the at least one metal ion in a reaction medium in the presence of at least a first organic compound, where the first organic compound is an optionally substituted monocyclic, bicyclic or polycyclic saturated or unsaturated hydrocarbon in which at least two ring carbons are replaced by heteroatoms selected from the group consisting of N, O and S, to form a reaction intermediate containing at least one metal ion and the first organic compound; and (b) reaction of the reaction intermediate at a prescribed temperature with an at least second organic compound which coordinates to the at least one metal ion, where the second organic compound is derived from a dicarboxylic, tricarboxylic or tetracarboxylic acid.

La présente invention concerne un procédé de fabrication d'un matériau de squelette métallo-organique poreux contenant au moins deux composés organiques coordonnés à au moins un ion métallique, ledit procédé comprenant les étapes suivantes consistant à : (a) oxyder au moins une anode contenant un métal correspondant à ou aux ions métalliques dans un milieu réactionnel en présence d'au moins un premier composé organique, le premier composé organique étant un hydrocarbure saturé ou insaturé, mono-, bi- ou polycyclique, éventuellement substitué, au moins deux atomes de carbone cyclique étant remplacés par des hétéroatomes choisis dans le groupe comprenant N, O et S, afin de former un produit réactionnel intermédiaire contenant le ou les ions métalliques et le premier composé organique; et (b) mettre à réagir le produit réactionnel intermédiaire à une température donnée avec au moins un second composé organique, coordonné à ou aux ions métalliques, le second composé organique dérivant d'un acide di-, tri- ou tétracarboxylique.
