Based on a dianhydride monomer 2,5- bis(3,4- dicarboxyphenoxy)-4''''''''''''''''-phenylethynyl biphenyl (PEPHQDA) containing a crosslinkable phenylethynyl pendant group, microporous polyimide networks (HBPI-CRs) were prepared through a two- step pathway combining polymerization and crosslinking reactions. Specifically microporous features such as surface morphology, microporous structure and uniform nanometer- sized pore channels were introduced to the polyimide networks through this two- step pathway. The HBPI- CR networks exhibited a BET surface area (385-497 m(2) g(-1)) as well as a comparable CO2 uptake (1.65- 2.04 mmol g(-1) at 273 K and 1 bar) and enthalpy of adsorption (28.6- 30.0 kJ mo(l-1)) to that of other microporous polyimides derived from rigid tri- dimensional monomers.
