The introduction of a base component to porous organic salts and their CO2 storage capability
Porous organic salts (POSs) are constructed by charge-assisted hydrogen bonding between amino and sulfonic groups, and can be used to design a variety of porous structures based on molecular design. In particular, triphenylmethylamine (TPMA) and aromatic sulfonic acids form robust POSs with a rigid...

| description | Porous organic salts (POSs) are constructed by charge-assisted hydrogen bonding between amino and sulfonic groups, and can be used to design a variety of porous structures based on molecular design. In particular, triphenylmethylamine (TPMA) and aromatic sulfonic acids form robust POSs with a rigid diamond structure (d-POSs). In this study, by replacing one of the three phenyl rings of TPMA with a pyrimidine ring, we succeeded in constructing a d-POS with high porosity (43.8%) and with a base component (pyrimidine) on the void surface. In addition, the weak basicity of the pyrimidine did not interfere with the formation of d-POSs. This d-POS adsorbed CO2 over the primary air components (N2 and O2) and also exhibited CO2 storage capability: It retained CO2 at a relatively low pressure of Pe/P0 = 0.05, and readily desorbed CO2 below Pe/P0 = 0.05. |
