Selective sorption of oxygen and nitrous oxide by an electron donor-incorporated flexible coordination network

Abstract

Incorporating electron donor functionalities into porous coordination frameworks enables the strong binding of electron-withdrawing guests, but such binding typically occurs irreversibly. Here, a structurally dynamic 2D coordination network incorporating an electron donating group is found to selectively and reversibly bind oxygen and nitrous oxide, while also exhibiting large structural deformations after guest removal.
