The properties of various mixtures of a zwitterionic ionic liquid (ZIs-1) and LiNTf2, including their conductivity, have been studied showing how they can be adjusted through their molar composition.
Supported ionic liquid-like phases (SILLPs) containing Rose Bengal (RB) units are used to develop organocatalytic systems for the cycloaddition of CO 2 to epoxides. The activity of the supported RB fragments can be fine-tuned by controlling the nature of the SILLPs (i.e., substitution at the imidazolium ring, crosslinking degree of the polymeric matrix, loading, etc.). Such a catalytic system prepared from cheap, simple, and commercially available components provides high activity and stability, with no decay in activity for at least 10 days of continuous use under flow conditions.
Developing efficient and sustainable methodologies to transform CO2 into added value chemicals is an important strategy to decarbonize the chemical industry. Here, a new multi-scale approach for the cycloaddition of...
The catalytic activity of Rose Bengal (RB) immobilized on supported ionic liquid (IL)‐like phases was evaluated as a polymer‐supported photocatalyst. In these systems, the polymer was designed to play a pivotal role. The polymeric backbone adequately modified with IL‐like moieties (supported IL‐like phases, SILLPs) was not just an inert support for the dye but controlled the accessibility of reagents/substrates to the active sites and provided specific microenvironments for the reaction. The structure of SILLPs could be finetuned to adjust the catalytic efficiency of the RB‐SILLP composites, achieving systems that were more active and stable than the related systems in the absence of IL‐like units.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
