1. A nanoporous material made of aggregated polymeric nanoparticles, wherein the polymer has a spatial conformation of open network comprising the repetitive hydrocarbon structure of formula I: wherein R1-R9 are molecular groups which bind with other structures of formula I, each independently selected from H, (C1-5) alkylene- or (C6-10) cycloalkylen-(C1-5) alkylene-; wherein the alkylene groups can be saturated or have one or more carbon-carbon double bonds, wherein the groups cycloalkylene have one or more carbon-carbon double bonds, and wherein one or more carbon atoms of the alkylene and cycloalkylene chains can be substituted by a —O— bridge or by —OH, and wherein at least 40% of the nanoparticles have a diameter above 50 nm.
