Synthesis of High Surface Area Microporous Spiro-Polymer for Green Chemistry Applications

Fadi Ibrahim

Three anthracene microporous polymers (AMPs) bridged by imide links were successfully prepared by conventional nucleophilic substitution reaction between different 9,10-dihydro-9,10- ethanoanthracenes and 2,3,5,6-tetrachlorophalonitrile (instead of fluoro-monomer)1,2. AMPs display a BET surface area in the range of 711-796 m2 g–1, and adsorb reach to 1.70 wt.% H2 at 1.09 bar/77 K. The enhanced microporosity, in comparison to other organic microporous polymers originates from the macromolecular shape of framework, as dictated by the anthracene units, which helps to reduce intermolecular contact between the extended planar struts of the rigid framework. The impressive hydrogen adsorption capture of these materials verified by Horvath-Kawazoe (HK) and NLDFT analyses of low-pressure nitrogen adsorption data, which expected to be use in transportation as a source of green chemistry.
