Multifunctional Polymers Based on Ionic Liquid and Rose Bengal Fragments for the Conversion of CO₂ to Carbonates

Supported ionic liquid-like phases (SILLPs) containing Rose Bengal (RB) units are used to develop organocatalytic systems for the cycloaddition of CO2 epoxides. The activity supported RB fragments can be fine-tuned by controlling nature SILLPs (i.e., substitution at imidazolium ring, cross-linking degree polymeric matrix, loading, etc.). Such a catalytic system prepared from cheap, simple, and commercially available components provides high stability, with no decay in least 10 days continuous use under flow conditions.
