“…In particular polarization transfer solid-state NMR (PTssNMR) was shown to provide molecular level information on the dissolved and insoluble fractions of cellulose in an aqueous medium (Gustavsson et al 2014). Self-diffusion NMR measurements were performed on several ionic liquids and mixture of ionic liquids with other solvents, like DMSO, mainly to demonstrate deviation from simple ideal mixing rules due to cellulose association with solvent ions (Youngs et al 2011;Hall et al 2012;Radhi et al 2015). Thus self-diffusion measurements can be used to investigate solvent-solute interactions.…”

Molecular self-diffusion coefficients were measured in solutions of microcrystalline cellulose (MCC) and dissolving pulp, in 40 wt% aqueous tetrabutylammonium hydroxide (TBAH), using pulsed field gradient stimulated echo NMR. From the cellulose diffusion coefficients, a weight averaged radius of hydration \R h [ w = 6.1 nm for MCC and \R h [ w = 15 nm for pulp were obtained. Water and TBA ? ions show a significantly different dependence on the cellulose concentration, revealing different molecular interactions with the polymer. Watercellulose are essentially excluded volume. TBA ? ions, on the other hand, bind to cellulose with approximately 1.2 TBA ? ions per glucose unit.

“…In 2002, Swatloski et al [14] used imidazolium based IL for the dissolution of cellulose, since then the use of ILs particularly imidazolium based ILs for the biomass dissolution and conversion of biomass to biocompatible or biodegradable materials has attracted both academic and industrial interests [19][20][21]. In order to understand the effect of ILs on biopolymer dissolution, studies have been further conducted on model compounds such as low molecular weight saccharides [3,[22][23][24][25][26]. Ebner et al [27] have studied the reactivity of butylmethylimidazolium ILs with D-glucose and reported that imidazolium cation reacts at C-2 atom of the cellulose model compound (D-glucose).…”

Room-temperature ionic liquids meet bio-membranes: the state-of-the-art

Room-temperature ionic liquids (RTIL) are a new class of organic salts whose melting temperature falls below the conventional limit of 100°C. Their low vapor pressure, moreover, has made these ionic compounds the solvents of choice of the so-called green chemistry. For these and other peculiar characteristics, they are increasingly used in industrial applications. However, studies of their interaction with living organisms have highlighted mild to severe health hazards. Since their cytotoxicity shows a positive correlation with their lipophilicity, several chemical-physical studies of their interactions with biomembranes have been carried out in the last few years, aiming to identify the molecular mechanisms behind their toxicity. Cation chain length and anion nature of RTILs have seemed to affect lipophilicity and, in turn, their toxicity. However, the emerging picture raises new questions, points to the need to assess toxicity on a case-by-case basis, but also suggests a potential positive role of RTILs in pharmacology, bio-medicine and bio-nanotechnology. Here, we review this new subject of research, and comment on the future and the potential importance of this emerging field of study.
