摘要：Metal-free materials with multicolor tunable circularly polarized luminescence (CPL) are attractive because of their potential applications in information storage and encryption. Here, we designed two enantiomers composed of chiral dialkyl glutamides and achiral vibration-induced emission (VIE) moiety, which can switch on CPL after a simple gelation process. It is noteworthy that the CPL colors vary in different solvents, and this is attributed to various self-assembly-induced microstructures, in which the VIE 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 information figure was constructed. To our satisfaction, the system possesses multiple information-storage functions. The orthogonal anticounterfeiting and CPL enhanced encryption functions also improve the system information encryption ability. In brief, this study provides a practical example of CPL applied to information security and an effective approach to obtain a single-component color-tunable CPL material with multiple information storage and encryption functions as well.
