With regard to a high void volume and surface area, nanoporous materials have been applied in a wide range of areas concerned with sorption, separation, sensing, and catalysis. They are categorized in accordance with the pore size, the solid morphology, or other criteria. Based on the IUPAC classification, they can be sorted three groups - microporous, mesoporous, and macroporous materials. Zeolites and Metal Organic Frameworks (MOFs) are typical examples of microporous materials with high crystallinity, and silica/ aluminosilicate-based porous materials (e.g., silica aerogels, M41-S type solids, etc) have meso pores. By virtue of high surface area and fast diffusional mass transfer of macromolecules, mesoporous materials, mainly consisting of pores range of 2 ~ 50 nm, are attracted for membrane, chromatography, and sensor.  However, most of mesoporous materials, built up from inorganic or organic-inorganic hybrid components, are collapsed by long term exposure to water. This leads to performance limitations in certain applications, notably the sorption of typical species in water, the catalytic reaction in aqueous media.Organic porous 3D networks have been explored as one of candidates overcoming such challenges for the inorganic and hybrid materials. The present work is dedicated to the development of a new class of organic nanoporous materials prepared by a radical polymerization of a functionalized crosslinker and an acryl derivative, which gives a route where all or most functional groups except the acryl group survive after network formation and solvent drying. Our objective is to demonstrate the feasibility of a time-efficient fabrication, the probability of the porous material as a new heterogeneous catalyst, and a sorption material, to highlight correlations between reaction parameters and these newly developed nanostructures.
