Abstract Porous ionic liquids prepared from phosphonium‐based and metal‐organic frameworks (MOFs) are fluid in large ranges of temperature including ambient. It is shown that the ion pairs too voluminous to enter pores MOF, so porous remain several months as suspensions with permanent free volume, capable absorbing quantities gases. The increase gas absorption, when compared pure liquids, proportional amount solid suspension. Structural features MOFs maintained suspensions. Thermodynamic...

In recent years, the fight against climate change and mitigation of impact fluorinated gases (F-gases) on atmosphere is a global concern.

Porous ionic liquids simultaneously absorb carbon dioxide and catalyse its reaction with epoxides to form cyclic carbonates under mild conditions.

The rheological behavior of porous ionic liquids comprising ZIF‐8 suspensions in two Newtonian — trihexyltetradecylphos‐ phonium bis(trifluoromethylsulfonyl)imide and tri‐ hexyltetradecylphosphonium chloride exhibited distinct unexpected differences. the bis(trifluoromethylsulfonyl)imide‐based liquid showed Bingham with a measurable yield stress, whereas those chloride‐based remained Newtonian, even at high solid volume fractions up to 17.4%. Remarkably, viscosities these were not...

Biocompatible cyclodextrin-based metal–organic frameworks (CD-MOFs) form porous suspensions when dispersed in ionic liquids.

Chemists aim to meet modern sustainability, health, and safety requirements by replacing conventional solvents with deep eutectic (DESs). Through large melting point depressions, DESs may incorporate renewable solids in task-specific liquids. Yet, DES design is complicated complex molecular interactions a lack of comprehensive property databases. Even measuring pure component properties can be challenging, due decomposition before melting. Here we overcame the quintessential constituent,...
