Cover Feature: Synthesis and Characterization of Hemiindigo‐Based Glycoside and Glycomacrocycle

Blue and green irradiation have been used to reversibly photoswitch a hemi-indigo-based glycomacrocycle from the Z- to the E-isomer, accompanied by on/off fluorescence photoswitching, as depicted in the pictures in the cavities of the molecules, as well as an off/on chiroptical switching, as represented by the helicity of the snail shell under the E-macrocycle. More details are provided in the Research Article by J. Xie and co-workers (DOI: 10.1002/chem.71764).
