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 .
