A brush with success : Responsive brushes composed of poly( N ‐isopropylacrylamide) grafted onto a poly(thiophene) backbone display the highest water solubility ever reported for a neutral poly(thiophene) as well as temperature‐dependent optical properties and water solubilities (see picture). The graft polymer exhibits shifts in the π–π* transition of the poly(thiophene) backbone near the collapse temperature of the poly( N ‐isopropylacrylamide) chains.
