Hydrophobic deep eutectic solvents (DESs) have gained increasing attention as sustainable and environmentally friendly alternatives to the conventional organic solvents. In this work, we prepared several new hydrophobic DESs based on lignin derivatives and characterized their physicochemical properties using experiments and molecular simulations. We investigated the melting point and thermal decomposition temperature of the new DESs using thermogravimetric analysis and the level of their hydrophobicity based on their static contact angle on a glass or plastics surface. Molecular simulations were conducted to investigate the structural and dynamic properties of molecular association, especially hydrogen bonds in these DESs. This work provides the promising role of lignin derivatives in developing hydrophobic DESs with features suitable for applications as solvent and extraction medium.
