“…Meanwhile, the accessible cavities of HCNS were not occupied. Likewise, in another more recent study, our group [73] reported MOF PLs by utilizing ZIF-67 and symmetric dicationic ILs based on non-covalent interactions (Figure 12e). Typically, the striking feature of as-prepared ZIFs PLs is the lowest viscosity (543.4 mPa S at 25 °C) till now.…”

Porous liquids (PLs), an emerging type of flowing liquid materials that combine the merits of porous solids and flowing liquids, have garnered immense attention since the concept of PLs was proposed in 2007. Meanwhile, PLs have witnessed growing success in versatile synthesis strategies and emerging applications, especially since 2017. Given the lack of a timely comprehensive review, developing a prompt summary with a comprehensive understanding is undoubtedly urgent. Thus, this critical review offers a comprehensive summary of the progress in fundamental chemistry, developmental history, synthetic strategies, and emerging applications of PLs. First, the fundamental chemistry and developmental history are reviewed. Then, the synthesis strategies of PLs are highlighted. Additionally, crosscutting studies of pure theoretical simulations are reviewed. Meanwhile, the daunting characterization issues of PLs are analyzed. Next, the state-of-the-art of PLs applications is reviewed in detail. In the end, perspectives regarding the remaining challenges and future directions for PLs are presented. It is speculated that this critical comprehensive review of PLs could inspire scientific communities who focus on the taskspecific materials for various applications, such as gas sorption, membrane separation, catalytic conversion, chiral separation, thermal management and electrolyte, and so on.

“…It has also been shown that bulky ionic liquids with different applications in energy storage device, [29] CO 2 capture, [30] toluene capture, [31] and lubrication [32] can be employed as green solvent [33,34] for the fabrication of porous liquids. For example, MOFs and zeolites with microporous/mesoporous frameworks have been utilized as host molecules in bulky ionic liquid medium to form another type of microporous/mesoporous liquids [35–43] . Further, meso‐ and microporous liquids have also been designed by surface engineering MOFs with oligomer species or polyethylene glycol, and also by the dissolution of MOFs in other solvents such as crown ethers and poly(dimethylsiloxane) [44–47] .…”

Permanent pores combined with fluidity renders flow processability to porous liquids otherwise not seen in porous solids. Although porous liquids have been utilized for sequestration of different gases and their separation, there is still a dearth of studies for deploying in situ chemical reactions to convert adsorbed gases into utility chemicals. Here, we show the design and development of a new type of solvent‐less and hybrid (meso‐)porous liquid composite, which, as demonstrated for the first time, can be used for in situ carbon mineralization of adsorbed CO2. The recyclable porous liquid composite comprising polymer‐surfactant modified hollow silica nanorods and carbonic anhydrase enzyme not only sequesters (5.5 cm3 g−1 at 273 K and 1 atm) and stores CO2 but is also capable of driving an in situ enzymatic reaction for hydration of CO2 to HCO3− ion, subsequently converting it to CaCO3 due to reaction with pre‐dissolved Ca2+. Light and electron microscopy combined with X‐ray diffraction reveals the nucleation and growth of calcite and aragonite crystals. Moreover, the liquid‐like property of the porous composite material can be harnessed by executing the same reaction via diffusion of complimentary Ca2+ and HCO3− ions through different compartments separated by an interfacial channel. These studies provide a proof of concept of deploying chemical reactions within porous liquids for developing utility chemical from adsorbed molecules.

“…Most recently, Xia et al reported the use of the cyclodextrin-derived Type-I porous liquid for the e cient chiral recognition and separation of nucleosides in the solution 36 . Except for the two examples above, current research on the host-guest properties of the molecular cage-based porous liquids has been mainly focused on the accommodation of small gaseous molecules such as carbon dioxide 8,37,38 , methane 11,14,39 and chloro uorocarbon 4 . It still remains a rare and poorly understood of the capture of non-gaseous guest molecules in porous liquids.…”

Porous liquids with chemical separation properties are quite well-studied in general, but there is only a handful of reports in the context of identification and separation of non-gaseous molecules. Herein, we report the first example of Type-II porous ionic liquid that exhibits exceptional selectivity towards L-tryptophan (L-Trp) over other aromatic amino acids and the first in which coordination cages promote this selectivity. A previously known class of anionic organic-inorganic hybrid doughnut-like cage (HD) has been readily dissolved in trihexyltetradecylphosphonium chloride (THTP_Cl). The resulting liquid, HD/THTP_Cl, is thereby composed of common components, facile to prepare, and exhibit room temperature fluidity. The permanent porosity are manifested by the high-pressure isotherm for CH4 and modeling studies. With evidence from time-dependent amino acid uptake, competitive extraction studies and molecular dynamic simulations, HD/THTP_Cl exhibit better selectivity towards L-Trp than existing solid state sorbents, and we attribute it to not only the intrinsic porosity of HD but also the host-guest interactions between HD and L-Trp. Specifically, each HD unit is binded with nearly 5 L-Trp molecules, which is higher than the L-Trp occupation in the structure unit of other benchmark metal-organic frameworks.
