摘要

The mimic of a (3,9)-connected xmz framework generates a novel highly connected Co-metal-organic framework (SNNU-80) constructed by trigonal prismatic [Co-3(OH)(COO)(6)] building blocks and tripodal pyridyldicarboxylate ligands (BPYDB = 4,4'-(4,4'-bipyridine-2,6- diyl)-dibenzoic acid). Compared to the nonporous Copyridine-3,5-dicarboxylate xmz metal-organic framework (MOF), the extension of a triangular linker leads to a different geometrical distribution of ligands and thus a porous structure with the topology of 3,3,9T2 for SNNU-80. Four types of polyhedral cages coexist together, which produce permanent micro- and mesoporosity. Different from MCF-18 assembled by BPYDB with [Ni-3(OH)(COO)(6)] showing drastic framework breathing, SNNU-80 is not flexible. As a result, SNNU-80 shows remarkable CO2 uptake capacity as well as high CO2 and, C-2 hydrocarbons over CH4 selectivity. Furthermore, the electrochemical measurements show that SNNU-80 is an idea electrode Material for supercapacitors due to its highly connected stable porous framework and the pseudocapacitor contribution introduced by the mixed valent system.
