“…24,25 This means that DESs can be extensively fine-tuned for specific applications and are cost-effective, green, and mostimportantly for biological applications, non-toxic. [26][27][28][29][30][31] In addition, many DESs are known glass formers which makes them extremely interesting for cryopreservation, and the potential role of natural deep eutectic solvents for desiccation and freezing tolerance in plants and animals has been mentioned in the literature. [32][33][34][35][36] Despite these promising properties, to date there have been few studies, to the authors' knowledge, exploring the use of DESs for cryopreservation of mammalian cells.…”

“…23 interactions with certain types of analytes compared to [Ch + ][Cl − ], despite similarities in their chemical structures. 21,23 Previously, Bryant et al highlighted that the presence of a carboxylate substituent and the absence of hydroxyl functional groups, as well as their surfactant-like nature in betaine HBAs compared to [Ch + ][Cl − ], is responsible for varied electrostatic interactions, 26 thereby imparting differences in their solvation properties. Like all other classes of DESs, the polarity of zwitterionic DESs is strongly influenced by the type of HBA and HBD and/or their molar ratio.…”

Deep eutectic solvents (DESs) formed by mixing zwitterionic hydrogen bond acceptors (HBAs) with diol- and organic acid-based hydrogen bond donors (HBDs) are popular sustainable solvents. In addition to possessing an amphiphilic character, zwitterionic DESs offer unique solvation properties, unlike those composed of halide-containing HBAs. While all other popular classes of DESs have been investigated, no study has attempted to characterize the solvation characteristics of zwitterionic DESs. In this study, the solvation properties of betaine [Bet]-, sulfobetaine-, and l-carnitine [l-Car]-based DESs were thoroughly investigated for the first time using solvatochromic dye methods and inverse gas chromatography (IGC). The Nile red polarity scale revealed that DESs composed of organic acids were generally more polar than diol-based DESs. Kamlet–Taft solvent parameters revealed that glycerol-based DESs offered exceptionally high hydrogen bond donating ability compared to those composed of 1,4-butane diol and triethylene glycol. The Abraham solvation parameter model revealed hydrogen bond basicity to be the most dominant interaction, and it was generally higher for diol-based HBDs compared to organic acid-based HBDs. Additionally, sulfobetaine HBAs possessing longer alkyl chains generally offered higher dispersive-type interactions and hydrogen bond basicity compared to [Bet] and [l-Car] salts. This is the first study to combine and compare results from solvatochromic dye methods and IGC in an attempt to comprehensively explain and predict the solvation characteristics of zwitterionic DESs.

“…Recently, due to the advantages of low cost, excellent biocompatibility, and high ionic conductivity over a wide temperature range (from subzero to high), ionic deep eutectic solvents have made great contributions to the progress of ionic gel sensors. − Polymerizable deep eutectic solvents (PDESs) − refer to the DES type formed by polymerizable hydrogen bond donors and hydrogen bond receptors. Elastomer materials that are transparent and stretchable can be obtained by polymerizing PDESs. − Luna-Bárcenas et al first reported thermal-initiated polymerization of acrylic-acid/choline-chloride DESs, which provided a new idea for PDES-based conductive elastomers.…”

Wearable elastic electronic devices have attracted tremendous attention due to their monitoring capabilities for human motion detection. In this work, a hydrogen bond acceptor quaternary ammonium salt, choline chloride (ChCl), has been used to fabricate deep eutectic polymer (DEP) blends with polyvinyl alcohol (PVA). The miscibility, molecular interaction, and physical properties of PVA/ChCl DEP blends were investigated systematically. It is demonstrated that the deep eutectic of PVA/ChCl can be obtained by simple solution blending, and the melting points of both PVA and ChCl are reduced respectively due to the strong hydrogen bond between PVA and ChCl. Due to the elasticity of the PVA/ChCl elastomer and the response of ChCl ions to temperature and humidity, the fabricated sensor showed stable and repeatable resistance changes upon strain, temperature, and humidity variations. We hypothesize that the DEP blend system has potential applications in functional composites and the final PVA/ChCl elastomer composites exhibited high transparent, antifreeze, and recyclable capability, which may be promising for applications in soft/flexible devices.
