Quest for 9-connected robust metal–organic framework platforms based on [M ₃ (O/OH)(COO) ₆ (pyridine) ₃ ] clusters as excellent gas separation and asymmetric supercapacitor materials

We demonstrate herein [M ₃ (O/OH)(COO) ₆ (pyridine) ₃ ] clusters an ideal building block for 9-connected metal–organic framework platforms toward gas uptake and separation and asymmetric supercapacitor multifunctional materials.
