Thumbnail image of graphical abstract

Polymeric organic network structures are synthesized using (methanetetrayltetra-4,1-phenylene)tetrakisboronic acid and three kinds of halogen-substituted struts that include heterocyclic groups. While the networks have moderate surface areas, they exhibit good capture and uptake capacities for CO2 and very high selectivity over CH4 and H2 at 298 K and under 1 bar gas pressure.
