Claim 5:
6. A process for preparing a polymer of the two-dimensional organic monomer according to claim 1, the process comprising:
charging hexaaminobenzene (HAB) and a dianhydride compound in a DMSO solvent to obtain a reaction mixture;
(ii) refluxing the reaction mixture under argon atmosphere for 20 hours to 24 hours;
(iii) distilling the reaction mixture at 170° C. to 190° C. and 0 atm to 5 atm pressure to obtain a solid;
(iv) centrifuging the solid obtained from (iii) and washing the centrifuged solid with water and acetone solvent;
(v) performing a soxhlet extraction on the solid obtained from (iv) with water, methanol, and acetone for 35 hours to 40 hours; and
(vi) drying the solid obtained from (v) under vacuum at 80° C. to obtain the polymer.
