Achieving a stable COF with the combination of"flat"and"twist"large-size rigid synthons for selective gas adsorption and separation
文献摘要：
A new type of covalent organic framework(COF)was achieved using combination of structrally rigid and conformationally othorganal building blocks.The N-2-aryl-substituted triazole derivative(NAT-CHO)was prepared with co-planar conformation among the three aromatic rings as the"flat"building block.The 4,4′,4″,4′-(ethene-1,1,2,2-tetrayl)tetraaniline)(ETTA)was applied as the"twist"building block.A 2D sheet of network was obtained through imine formation.The resulting NAT-COF gave excellent thermal and chemical stability,survived aqueous solutions from pH 5 to 13.With large-size building blocks,the porous framework NAT-COF gave efficient gas adsorption with excellent selectivity of C3 propane over C1 me-thane,suggesting its potential application for selective gas capture and separation.
