Design of Flexible Lewis Acidic Sites in Porous Coordination Polymers by using the Viologen Moiety

Charged up: A novel porous coordination polymer with a charged organic surface (COS) comprising a zwitterionic organic linker, viologen, has been synthesized. The COS shows strong Lewis acidity accompanied with flexibility, and the isosteric heat of H2 adsorption is 9.5 kJ mol−1, which is comparable...

Zusammenfassung:Charged up: A novel porous coordination polymer with a charged organic surface (COS) comprising a zwitterionic organic linker, viologen, has been synthesized. The COS shows strong Lewis acidity accompanied with flexibility, and the isosteric heat of H2 adsorption is 9.5 kJ mol−1, which is comparable to that of open metal sites (OMSs).
