Preparation of anionic nanoporous polymers with different counter cations in the pore Nanoporous polymers with carboxylic acid functionalized pores were treated with 0.1M aqueous solutions of the hydroxide salts of Li +, Na +, K +, Cs + and NH 4 + ions for 5h. The formation of a porous polymers with COOLi, COONa, COOK, COOCs, and COONH 4 groups at the pore surface, was confirmed by FTIR. The COOH st. band was shifted from 1685 to 1560 and 1404 cm 1 (Figure S7). C=O st asym(coo ) C=O st (COOH) C=O st sym(coo ) NH 4 + Absorbance (a.u.)
