A 2D microporous electron-rich porous aromatic framework JUC-Z2 with high physicochemical stability and large surface area was studied in detail for their low-pressure N-2, Ar, H-2, CO2, CH4 sorption. Its hydrogen, methane, and carbon dioxide storage capacities are 181 cm(3) g(-1) (77 K/760 mmHg), 25 cm(3) g(-1) (273 K/760 mmHg), and 71 cm(3) g(-1) (273 K/760 mmHg), respectively. Gas molecule recognition at 273 K was performed and results show only greenhouse gases such as carbon dioxide and methane could be adsorbed onto JUC-Z2.
