Porous organic frameworks (POFs) have been synthesized by Yamamoto-type Ullmann cross-coupling reaction using tetrakis (4-bromophenyl) methane (TBPM) and poly-4-bromostyrene (PBS) as monomers. Among these POFs, JUC-Z13 synthesized solely from PBS is found to be microporous (1.27 nm) and S-BET = 372 m(2) g(-1), and copolymerization with TBPM results in POFs with apparent surface areas up to 3137 m(2) g(-)1 and pore size up to 1.41 nm. Interestingly, JUC-Z14 and JUC-Z15 show hierarchical porosity. Low pressure gas uptake experiments on activated JUC-Z13-JUC-Z19 show enhanced gas storage capacities and isosteric heats of sorption (Qst) among porous materials.
