Synthesis of 1,3,5,7-tetrakis(4-cyanatophenyl)-adamantane and its microporous polycyanurate network for adsorption of organic vapors, hydrogen and carbon dioxide

This report presents the synthesis of a tetraphenyladamantane-based microporous polycyanurate network with a BET surface area of 843 m(2) g(-1) and a pore size of 7.8 angstrom. It uptakes 98.0 wt% benzene (298 K, P/P-0 = 0.9), 1.49 wt% H-2 (77 K/1 bar) and 12.8 wt% CO2 (273 K/1 bar) with CO2/N-2 selectivity of up to 112.
