title: Unusual solvent effects on chiroptical properties of an optically active regioregular polythiophene in solution.
abstract: The chiroptical properties of a novel, optically active regioregular poly[3-(4-((R)-4-ethyl-2-oxazolin-2-yl)phenyl)thiophene] (poly-1) were investigated in mixtures of a good solvent, chloroform, and a variety of poor solvents using CD spectroscopy. Most poor solvents induced CD on poly-1 with similar Cotton effects, while acetonitrile and nitromethane caused dramatic changes in the Cotton effects of poly-1.
