Room-Temperature Liquid Crystalline Tetraphenylethylene-Surfactant Complex with Chiral Supramolecular Structure and Tunable Circularly Polarized Luminescence

A novel room-temperature liquid crystal of tetraphenylethylene derivative (TPE-DHAB) was synthesized using an ionic self-assembly strategy. The TPE-DHAB complex exhibits typical aggregation-induced emission properties and a unique helical supramolecular structure. Moreover, the generation and handedness inversion of circularly polarized luminescence (CPL) can be achieved through further chiral solvation, providing a facile approach to fabricate room-temperature liquid crystalline materials with controllable supramolecular structures and tunable CPL properties through a synergistic strategy of ionic self-assembly and chiral solvation process. A room-temperature liquid crystal with a helical structure and tunable CPL was fabricated by a synergistic strategy of ionic self-assembly and chiral solvation. This material exhibits aggregation-induced emission (AIE) properties and a helical structure without inherent chirality. Chiral solvation imparts TPE-DHAB with a preferred handedness, enabling tunable circularly polarized luminescence (CPL) when using a chiral solvent. image
