We have synthesized poly(phenylacetylene)s bearing a maltohexaose. These polymers had a predominantly one-handed helical conformation. In addition, the polymers exhibited a solvatochromism with a chiroptical change accompanied by the helical conformational change. Thus, this novel stimulus responsive glycoconjugate should be applied to advanced materials capable of sensing various biological molecules, such as a lectin and virus.
