Understanding The Micro-Viscosity of Deep Eutectic Solvents and Ionic Liquids Using Fluorecents Molecular Rotor as A Probe

Abstract

Traditional organic molecular solvent is harmful due to their volatility. Green solvents like deep eutectic solvents (DESs) and ionic liquids (ILs) has emerged as alternatives as they are non-volatile but highly viscous. Hence, this has aroused the need for an extensive comprehension of the green solvent characterization specifically on their viscosity at molecular level.
