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.
