Preparation of Microporous Organic Polymers via UV-Initiated Radical Copolymerization.

UV-initiated radical copolymerization has been successfully applied for the preparation of two kinds of microporous organic polymers (MOPs) based on divinylbenzene (DVB)/bismaleimide (BMI) monomers and DVB/pentaerythritol tetraacrylate (PET4A). The obtained MOPs exhibit high BET surface areas and good CO 2 storage performance. The maximum BET surface areas of DVB/BMI and DVB/PET4A are 585 and 887 m 2 g -1 , respectively. Furthermore, the ester groups embedded on the DVB/PET4A copolymer skeleton can be easily converted into carboxylic groups by hydrolysis and show superior adsorption capacity of 485 mg g -1 toward methylene blue dye. The adoption of this highly efficient polymerization strategy offers the possibility for the economical and continuous preparation of MOPs and demonstrates great potential for industrial application.
