Conformational preference of a porphyrin rotor in confined environments

Abstract

The amount of twisted conformation of a porphyrin rotor, when confined within ionic liquid reverse micelles, increased as compared to the neat solvents within a set of 1-alkyl-3-methylimidazolium ionic liquids. A similar trend was noted within DMSO-containing reverse micelles, indicating that the confinement might be a major contributor in the control of the rotor's conformation. © The Royal Society of Chemistry 2014.
