Synthesis of Type II Porous Liquids from Nonporous Metal–Organic Polyhedra Enhanced by Host–Guest Complexation

selectivity. This strategy can be extended to the fabrication of additional Type II PLs, showing its universality. This synergistic design concept integrating supramolecular chemistry with PLs not only overcomes traditional tedious covalent modification but also enables high compatibility between apolar cage solutes and polar solvents, affording PLs with high porosity, low volatility and viscosity, and programmable tunability.
