Microporous Metal-Organic Framework Based on Ligand-Truncation Strategy with High Performance for Gas Adsorption and Separation

摘要

By using the ligand-truncation strategy, a microporous metal-organic framework (1) with high surface area was designedly synthesized. MOF 1 shows a new (4, 4)-connected net with a Schlafli symbol of (4(4).6(2))(4(3).6(2).8)(2)(4(2).8(2).10(2)) and exhibits a high H-2 capture capacity (193 cm(3) g(-1) at 1 atm and 77 K) and selectivities for CO2 over N-2 and CH4 at low pressure.
