Abstract/OtherAbstract:
Two enantiomeric light-driven azo molecular switches, with axial chirality and extended conjuga-tion, were found to exhibit unprecedented reversible photoisomerization in both organic solvent and liquid crystal media only upon visible-light irradiation. The chiral switch, doped in an achiral liquid crystal with different concentration, was able to either immediately induce an optically tunable helical superstructure or still retain achiral liquid crystal phase whose helical superstructure was induced and tuned reversibly upon visiblelight irradiation. Furthermore, reversible dynamic red, green and blue reflection, achieved only by using visible light, was demonstrated.
