“…For many years, we observed a continuous interest in ionic liquids’ (ILs) research. ILs owe their interest due to their versatility and unique properties, which allowed them to find wide utilization in various fields . A very low level of volatility, an ionic structure in the liquid state below 100 °C, and a great variety of combinations of cations and anions are just some of them .…”

Research on ionic liquids is constantly providing information on their new and more advanced applications. Undoubtedly, the use of latent curing agents for epoxy resins is one of the most interesting applications of this group of compounds. In this work, a detailed description of the synthesis and physicochemical studies of DABCO-based (1,4-diazabicylo[2.2.2]octane) ionic liquids is presented. Their most valuable feature is that they can be latent curing agents for polymerization of epoxy resins, which in turn can be used, when combined with fibers, as composites with special, new properties. The research includes detailed discussion of synthesis of new DABCO-ILs, focusing on obtaining pure compounds and expanding current knowledge on the subject. Thermal (DSC) and chromatographic (IC) properties have been discussed for all presented salts. Furthermore, ionic liquids with dicyanamide and triflate anion have demonstrated the ability to initiate polymerization of epoxy resins. Subsequently, all mixtures were cured into cubical shape and were subjected to the Shore hardness test (SHT). The main advantages of the obtained ILs are (i) the ability to store ionic liquids/epoxy resin mixture for prolonged periods of time without deterioration of curing properties and (ii) a significantly lower quantity of ionic liquids used in the process of curing epoxy resins.

CO2 levels in the atmosphere are increasing exponentially. The current climate change effects motivate an urgent need for new and sustainable materials to capture CO2. Porous materials are particularly interesting for processes that take place near atmospheric pressure. However, materials design should not only consider the morphology, but also the chemical identity of the CO2 sorbent to enhance the affinity towards CO2. Poly(ionic liquid)s (PILs) can enhance CO2 sorption capacity, but tailoring the porosity is still a challenge. Aerogel’s properties grant production strategies that ensure a porosity control. In this work, we joined both worlds, PILs and aerogels, to produce a sustainable CO2 sorbent. PIL-chitosan aerogels (AEROPILs) in the form of beads were successfully obtained with high porosity (94.6–97.0 %) and surface areas (270–744 m2/g). AEROPILs were applied for the first time as CO2 sorbents. The combination of PILs with chitosan aerogels generally increased the CO2 sorption capability of these materials, being the maximum CO2 capture capacity obtained (0.70 mmol g−1, at 25 °C and 1 bar) for the CHT:P[DADMA]Cl30% AEROPIL.

BACKGROUND Development of new plant protection strategies has become an urgent matter in modern agriculture, in view of the evidently proved negative effect of currently used active ingredients of pesticides. In recent years, much effort has been made to eliminate the use of pesticides established to be toxic to pollinators. RESULTS In this study, we present a group of new bifunctional ionic liquids based on dodine (N‐dodecylguanidine) cation whose physical and biological properties have been modified relative to those of the commercially available N‐dodecylguanidine acetate. The decreased level of residue of active substances in plant tissues reduces their availability to pollinators, which increases the safety of their use. Moreover, lower environmental impact in combination with high antifungal activity and an additional biological function, that is the systemic acquired resistance induction, are in line with the goals of sustainable agriculture. CONCLUSION The presented approach shows the possibility of derivatization of commonly used fungicide into the form of bifunctional salts whose physical and biological properties can be easily modified. The paper reports successful design and synthesis of new sustainable and green chemicals for the modern agriculture, being less toxic to the environment and human health but still effective against pathogens. © 2021 Society of Chemical Industry.
