  • Chiral aggregation-induced emission luminogens with delayed fluorescence for circularly polarized organic light-emitting diodes
    Patent number: 11871662
    Abstract: Provided herein are chiral compounds that exhibit circularly polarized photoluminescence and electroluminescence and electroluminescent devices and circularly polarized fluorescent probes comprising the same.
    Type: Grant
    Filed: February 14, 2019
    Date of Patent: January 9, 2024
    Assignee: The Hong Kong University of Science and Technology
    Inventors: Benzhong Tang, Fengyan Song
  • Compounds with circularly polarized luminescence
    Patent number: 11118111
    Abstract: The present subject matter relates to a fluorescent compound having aggregation-induced emission (AIE) characteristics. The compound can be a rod-like chiral luminogen bearing a chiral moiety at one end and long aliphatic chains at an opposing end. The compound emits circularly polarized light or luminescence (CPL) in the aggregate state. For example, the compound does not exhibit a chiroptical signal when dispersed in solution, but demonstrates tunable CPL signals in the aggregate state.
