Microporous organic polymers with high surface area are widely used in many applications.Among them,hypercrosslinked polymers have been extensively concerned because of their simple processes and low-cost reagents.However,due to most state-of-the-art strategies for HCPs based on condensation reactions,the release of small molecules such as hydrochloric acid and methanol involved in such strategies brings about new hazards to environment.Herein,we propose a method of fabrication of hypercrosslinked polymers via self-addition polymerization of divinyl benzene and its crosslinking with polar aromatic molecules.The hypercrosslinked polyDVB-based products are demonstrated by Friedel-Crafts addition reaction of double bonds on DVB that can connect adjacent phenyl rings of aromatic molecules to form the crosslinked networks.The HCPDVB-CB obtained in 1-chlorobutane as solvent has a high micropore content and displays high surface area up to 931 m2/g.Following this finding,DVB is used as a novel external crosslinker for knitting polar aromatic molecules.When L-phenylalanine and bisphenol A are used as the aromatic units,the obtained HCP(Phe-DVB) and HCP(BPA-DVB) could reach surface area of 612 and 471 m2/g,and have hydrogen uptake of 0.62 wt％ and 0.58 wt％ at 77 K and 1.13 bar by comparison with HCPDVB-CB having hydrogen uptake of 0.30 wt％,respectively.
