Summary: Space confined reactions are a viable strategy for achieving important properties in functional materials. Various systems for confinement have been reported, but the focus has primarily been on the concept of space confinement while neglecting the changes in confined space itself. Supercritical CO2 has the potential to reveal structural changes in confined spaces, known as the anti-nanoconfinement effect, which can lead to a series of variations in electronic band and structural transformation.

Summary: This study investigated the effect of adding a small amount of ethanol cosolvent in supercritical CO2 on the solvation structure and dynamics of caffeine in a mixed supercritical solvent using a systematic multiscale molecular modeling approach. The results showed that the local mole fraction of ethanol around caffeine increased due to the formation of hydrogen bonds between caffeine and its nearest ethanol molecules, which became less pronounced as the pressure of the system increased.
