Abstract
Chemically and thermally stable covalent organic framework (COF) materials are configured and operative as solid adsorbents for capturing gases and water.
Claims6
A composition comprising a porous crystalline covalent organic framework (COF), constructed from a tetratopic linker 1,1,2,2,-tetrakis (4-aminophenyl) ethene [ETTA, C26H16(NH2)4] and a tritopic linker 1,3,5-triformylbenzene [TFB, C6H3(CHO)3], termed COF-432 {[ETTA)3(TFB)4]imine}, which exhibits a mtf topology.
