Adding external, remote, and dynamic control to self-organized superstructures with desired properties is an important leap necessary in leveraging the fascinating mol. subsystems for employment in applications. Here two novel light-driven dithienylethene chiral mol. switches possessing remarkable changes in helical twisting power during photoisomerization as well as very high helical twisting powers were found to experience photochem. reversible isomerization with thermal stability in both isotropic organic solvents and anisotropic liquid crystal media. When doped into a com. available achiral liquid crystal host, the chiral switch was able to either immediately induce an optically tunable helical superstructure or retain an achiral photoresponsive liquid crystal phase whose helical superstructure was induced and tuned reversibly upon light irradiation Moreover, reversible light-directed red, green, and blue reflection colors with thermal stability in a single thin film were demonstrated.
