The breadth and importance of polymerized ionic liquids (PILs) are steadily expanding, and this review updates advances and trends in syntheses, properties, and applications over the past five to six years. We begin with an historical overview of the genesis and growth of the PIL field as a subset of materials science. The genesis of ionic liquids (ILs) over nano to meso lengthscales exhibiting 0D, 1D, 2D, and 3D topologies defines colloidal ionic liquids, CILs, which compose a subclass of PILs and provide a synthetic bridge between IL monomers (ILMs) and micro to macroscale PIL materials. The second focus of this review addresses design and syntheses of ILMs and their polymerization reactions to yield PILs and PIL-based materials. A burgeoning diversity of ILMs reflects increasing use of nonimidazolium nuclei and an expanding use of step-growth chemistries in synthesizing PIL materials. Radical chain polymerization remains a primary method of making PILs and reflects an increasing use of controlled polymerization methods.Step-growth chemistries used in creating some CILs utilize extensive cross-linking. This cross-linking is enabled by incorporating reactive functionalities in CILs and PILs, and some of these CILs and PILs may be viewed as exotic cross-linking agents. The third part of this update focuses upon some advances in key properties, including molecular weight, thermal properties, rheology, ion transport, self-healing, and stimuli-responsiveness. Glass transitions, critical solution temperatures, and liquidity are key thermal properties that tie to PIL rheology and viscoelasticity. These properties in turn modulate mechanical properties and ion transport, which are foundational in increasing applications of PILs. Cross-linking in gelation and ionogels and reversible step-growth chemistries are essential for self-healing PILs. Stimuli-responsiveness distinguishes PILs from many other classes of polymers, and it emphasizes the importance of segmentally controlling and tuning solvation in CILs and PILs. The fourth part of this review addresses development of applications, and the diverse scope of such applications supports the increasing importance of PILs in materials science. Adhesion applications are supported by ionogel properties, especially crosslinking and solvation tunable interactions with adjacent phases. Antimicrobial and antifouling applications are consequences of the cationic nature of PILs. Similarly, emulsion and dispersion applications rely on tunable solvation of functional groups and on how such groups interact with continuous phases and substrates. Catalysis is another significant application, and this is an historical tie between ILs and PILs. This component also provides a connection to diverse and porous carbon phases templated by PILs that are catalysts or serve as supports for catalysts. Devices, including sensors and actuators, also rely on solvation tuning and stimuliresponsiveness that include photo and electrochemical stimuli. We conclude our view of applications with 3D printi...

“…Owing to their excellent properties, ILs have been utilized as the functional monomers for preparation of MIPs [88]. Generally speaking, IL-based MIPs involve multiple interactions between the analyte and ILs (i.e., π-stacking, electrostatic, hydrophobic interactions, and hydrogen bonding) [89][90][91]. IL-based molecularly imprinted polymers (IL-MIPs) have aroused widespread concern as recognition materials because of their easy preparation, predictable specific recognition capability, high stability, high binding capacities and watercompatibility [92].…”

Natural products with a variety of pharmacological effects are important sources for commercial drugs, and it is very crucial to develop effective techniques to selectively extract and isolate bioactive natural components from the plants against the background of sustainable development. Ionic liquids (ILs) are a kind of designable material with unique physicochemical properties, including good thermal stability, negligible vapor pressure, good solvation ability, etc. ILs have already been used in pharmaceuticals for extraction, purification, drug delivery, etc. It has been reported that multi-interactions, like hydrogen bonding, hydrophobic interactions, play important roles in the extraction of bioactive components from the plants. In this review, recent progress in the understanding of scientific essence of hydrogen bonding, the special interaction, in ILs was summarized. The extraction of various natural products, one important area in pharmaceutical, by conventional and functional ILs as well as the specific roles of multi-interactions in this process were also reviewed. Moreover, problems existing in bioactive compound extraction by ILs and the future developing trends of this area are given, which might be helpful for scientists, especially beginners, in this field.

“…Currently, external factors 49 such as electric current, 50‐56 light 57‐63 or ultrasonication 64‐68 are the most influential among control systems in ATRP techniques with low catalyst loading. In this field, electrochemically mediated ATRP ( e ATRP) provides a precise control of the ratio between Cu I and Cu II during polymerization process, followed by receiving well‐defined materials by avoiding an undesirable termination reaction and gelation with the increase of molecular weight 69‐72 . The phenomenon of this method lies in the application of constant current ( I ) or potential ( E ) at the working electrode (WE) surface, thus ensuring the highly precise ratio of the concentration between oxidized and reduced form of the catalyst complex 37,73‐75 .…”

Troxerutin, a naturally occurring flavonoid glycoside, has a variety of beneficial activities characteristic for flavonols, such as strong antioxidant and anti-inflammatory properties. Besides the beneficial effects of troxerutin, limitations such as bioavailability have disrupted its application and prompt scientists to look for effective modification methods. This work presents the synthesis of troxerutin-based macromolecules with lipophilic poly(n-butyl acrylate) (PnBA) star arms via "core-first" procedure in a two-step synthetic route. Troxerutin as a polyphenol structure with ubiquitous reactive hydroxyl groups was for the first time modified with α-bromoisobutyryl bromide to receive an atom transfer radical polymerization (ATRP) initiator with 10 brominated initiation sites. The further step involved the synthesis of novel star-like macromolecules with troxerutin core and PnBA star arms by simplified electrochemically mediated ATRP (seATRP) in an environmentally friendly reaction medium-miniemulsion. Electrolysis under constant current conditions with temporal control was implemented, resulting in well-defined star-like polymers with complete preservation of chain-end functionality after restarting the synthesis. Hydrophobic properties of received troxerutin-based macromolecules were investigated by contact angles (Θ) measurements, followed by the free surface energy (FSE) calculations.
