On page 3525, Susumu Kitagawa and co-workers demonstrate a new porous coordination polymer, in which the uniform 1D channel and open metal sites lead to excellent methane separation capability towards carbon dioxide and C2 hydrocarbons at ambient temperature. More importantly, its high water- and acid/alkaline-resistance properties will pave the way for practical use for methane purification in the future.
