Pseudo-2D Porous Networks via Interpenetration of 1D Zigzag Ladder-type Coordination Polymers: Adsorption and Separation of Xylene Isomers

Self-assembly of AgPF6 with a new C3-symmetric tridentate N-donor ligand gives rise to unusual pseudo-2D porous networks with open channels via the interpenetration of 1D zigzag ladders. The open-channel networks selectively adsorb only m-xylene from the mixture of o- and m-xylene, with o-xylene thus acting as a channel-entrance stopper at room temperature. This system exemplifies unprecedented separation of o- and m-xylene.
