Tóm tắt

Chiral luminescent materials have garnered increasing attention for their exceptional ability to emit circularly polarized luminescence (CPL) along with their excellent applications. Here, a cyclohexylidene scaffold was conceptualized as a chiral source for developing higher-performance CPL materials in terms of simultaneously enhanced quantum yields (PLQYs) and dissymmetry factor. It was found that the axially chiral scaffold attached with a cyanostilbene showed a pathway-dependent assembly route to form chiral luminescent liquid crystals and crystals upon fast and slow cooling, respectively. A significant enhancement of PLQYs (98.4%) and a dissymmetry factor (g
