摘　　要：Multifunctional iodoaryl monomers were used for the catalyst- and solvent-free generation of microporous polymer networks of high surface areas up to 732mEg-1. The thermal conversion of the monomers relies on the homolytic cleavage of weak iodine-carbon bonds followed by a C-C coupling of the radicalic intermediates. By using tri- or tetrafunctional monomers and by tuning reaction temperature and time, the optimum reaction conditions allow the formation of the corresponding microporous networks in good yields of 71%-86%. The resulting networks exhibit notable high CO2 and H2 adsorption capacities of up to 8.89 wt% （273K, 1 bar） and up to 1.31 wt% （77K, 1 bar）, respectively.Multifunctional iodoaryl monomers were used for the catalyst-and solvent-free generation of microporous polymer networks of high surface areas up to 732 m^2 g^(-1).
