New Porphyrin-Based Metal−Organic Framework with High Porosity: 2-D Infinite 22.2-Å Square-Grid Coordination Network

Abstract
A new 2-D coordination network with 22.2-A square-grid coordination networks was prepared from a dicopper(II) tetraacetate [Cu2(AcO)4] as a linear linker motif and 5,10,15,20-tetra-4-pyridyl-21H,23H-porphine (H2TPyP) as a four-connected vertex, forming a regular high-porous structure. The characterization by N2 adsorption indicated that this coordination network has uniform micropores and gas adsorption cavities.
