Solid Solutions of Soft Porous Coordination Polymers: Fine-Tuning of Gas Adsorption Properties

My flexible friend: Separation of a CO2/CH4 mixture was optimized by varying the composition of solid solutions of interdigitated 2D frameworks comprising two different isophthalate ligands (see picture). The characteristics of the solid solutions were dependent on the ligand ratio, which influenced the inherent flexibility and therefore the adsorption properties of the frameworks.
