Abstract: Supramolecular assembly strategy is widely applied to develop circularly polarized luminescence (CPL) materials, especially for centrally chiral systems. The CPL sign of supramolecular gels based on a centrally chiral compound is generally regulated by employing the opposite chiral enantiomers. However, controlling CPL signals by regulating the interaction model between the achiral fluorophore and chiral gelator, accompanied by the adjustment of the emission wavelength, remains challenging. Herein, we have developed binary supramolecular gels based on achiral cyanostilbene derivatives and a chiral gelator. Two binary supramolecular gels have displayed achiral fluorophore-induced CPL sign inversion, attributed to the hydrogen bonding interaction between the carboxyl group of two fluorophores and the amino group of chiral gelator. This work reveals a rational approach to the design of CPL material with tunable CPL sign and CPL emission wavelength.
