A set of functionalized nanoporous materials are disclosed exhibiting a framework including metal atoms, oxygen atoms and at least one aromatic organic group containing more than one aromatic ring. The gas adsorption activity and, in particular, the molecular hydrogen uptake of the nanoporous material with increased aromaticity content is further enhanced by peculiar functionalization performed by integrating in the framework and/or on its surface actives moieties such as metal atoms, organic groups or sulfonic groups different from those of the starting framework. L'invention porte sur un ensemble de matières nanoporeuses fonctionnalisées qui présentent une ossature comprenant des atomes de métaux, des atomes d'oxygène et au moins un groupe organique aromatique contenant plus d'un cycle aromatique. L'activité d'adsorption des gaz, et, en particulier, l'absorption d'hydrogène moléculaire de la matière nanoporeuse avec contenu d'aromaticité augmenté, est encore renforcée par une fonctionnalisation particulière assurée par l'intégration dans l'ossature et/ou sur sa surface des moitiés actives telles que des atomes de métaux, des groupes organiques ou des groupes sulfoniques différents de ceux de l'ossature de départ.
