Eutectic solvents and low molecular weight gelators for next-generation supramolecular eutectogels: a sustainable chemistry perspective

Abstract

Eutectic solvents (ESs) have received a great deal of attention due to their advantageous physicochemical properties, low cost and high sustainability. Immobilization in gels greatly expands the combinatorial playground offered by these materials. Among the different strategies, the obtainment of supramolecular eutectogels by ES self-assembling in the presence of low molecular weight organic gelators is one of the most flourishing. This critical review highlights the advances in the last five years, introducing the different types of emerging supramolecular eutectogels and their main applications. A judicious analysis of opportunities and challenges is also discussed, identifying future optimisation directions. The recent literature is critically reviewed in light of the connection between the theory/practice of Green chemistry and the achievements of the UN Sustainable Development Goals.
