摘要：Metal-free materials with multicolor tunable circularly polarized luminescence (CPL) are attractive be-cause of their potential applications in informationstorage and encryption. Here, we designed two enantiomers composed of chiral dialkyl glutamides andachiral vibration-induced emission (VIE) moiety,which can switch on CPL after a simple gelationprocess. It is noteworthy that the CPL colors vary indifferent solvents, and this is attributed to variousself-assembly-induced microstructures, in which theVIE moiety is restrained to different degrees.Accordingly, a multidimensional code system composed of a quick response code, a ultraviolet (UV)light-activated color code, and a CPL informationfigure was constructed. To our satisfaction, thesystem possesses multiple information-storage functions. The orthogonal anticounterfeiting and CPL-enhanced encryption functions also improve thesystem information encryption ability. In brief, thisstudy provides a practical example of CPL applied toinformation security and an effective approach toobtain a single-component color-tunable CPL material with multiple information storage and encryptionfunctions as well.
