Effect of ionic liquids on the conformation of a porphyrin-based viscometer

Abstract

Structure of the cationic and anionic counterparts of ionic liquids has a significant impact on the conformational bias of the porphyrin rotor; an apparent correlation between the conformation and the viscosity of ionic liquids was noted, albeit it was found to be distinct and more complex from that found in molecular solvents. © 2013 The Royal Society of Chemistry.
