The design and application of green solvents mark a significant advancement in sustainable chemistry, addressing environmental concerns while preserving the efficiency and selectivity of chemical processes. This focus on green solvents such as ionic liquids (ILs) and deep eutectic solvents (DESs) which offer compelling properties such as low volatility, tunable polarity, and high thermal and chemical stability. The development of green solvents is deeply rooted in a strong foundation of chemical physics, physical chemistry, electrochemistry, green chemistry, and theoretical and computational chemistry. Understanding their properties and interactions at the molecular level is critical for industrial applications and sustainability goals. Investigations into the thermodynamic properties of liquid mixtures provide essential data for optimizing solvent performance under industrial conditions. Studies on liquid-liquid equilibria involving ILs and DESs offer insight into phase behaviour critical for separation and purification processes. Synthesis of eco-friendly corrosion inhibitors demonstrates the role of green chemistry in materials protection, while the green synthesis of nanomaterials opens pathways for applications in catalysis, sensing, and industrial processing. Furthermore, the contribution of green solvents to energy storage and conversion through the development of safer, more sustainable materials and electrolytes highlights their pivotal role in next-generation energy technologies.

The Research Topic will focus on the development and application of green solvents, grounded in the fundamentals of chemistry such as molecular interactions, solubility principles, reaction kinetics, and thermodynamics, to address various industrial challenges. This focus is essential, as it emphasizes and advocates for the use of environmentally friendly solvents to enhance and optimize industrial processes. This also includes the experimental and computational approach. Green solvents, designed with a deep understanding of chemical properties and behaviours, can significantly reduce the toxicological impact of traditional solvents, minimize environmental waste, and improve reaction efficiency and selectivity. By aligning chemical reactivity with sustainability, these solvents contribute to greener synthesis pathways and more controlled industrial operations.

The Research Topic aims to enhance the fundamental understanding of green solvents by exploring their molecular properties and behaviour. It seeks to highlight innovative applications of ionic liquids and deep eutectic solvents in fields such as catalysis, materials synthesis, corrosion protection, and energy technologies. The Topic also encourages interdisciplinary research that integrates chemistry, materials science, and chemical engineering.
