A paper entitled Complex Coacervation of Polymerized Ionic Liquids in Non-aqueous Solvents was recently published in ACS Polym. Au. by Minjung Lee*, Sarah L. Perry*, and Ryan C. Hayward.* This study provides insight into the effects of low-dielectric-constant solvents on complex coacervation, which has not been widely studied because of the limited solubility of conventional polyelectrolytes in these media.
