Circularly polarized electroluminescence (CPEL) has potential application in optical data storage and processing. It was recently discovered that CPEL could be generated from chiral‐substituted, conjugated polymers. These authors have synthesized a range of polyfluorenes (e.g., see Figure) that form liquid crystals and emit bluish light with a significant (200 times greater than in the first report) circularly polarized component.
