  • Organic light emitting diode having an emitter layer with a host and an emitter and having a triplet injection layer comprising the emitter, and methods of use thereof
    Patent number: 11889758
    Abstract: Disclosed herein are organic light emitting diode (OLED) devices and methods of use thereof. In one embodiment, an organic light emitting diode (OLED) device includes an emitting layer including: a host and an emitter, wherein the host exhibits triplet-triplet annihilation up-conversion, wherein the emitter has a band gap and exhibits triplet-triplet annihilation up-conversion, wherein the host and the emitter are different, and wherein the emitter has a concentration of 5% or more in the emitting layer.
    Type: Grant
    Filed: April 3, 2019
    Date of Patent: January 30, 2024
    Assignee: NORTH CAROLINA STATE UNIVERSITY
    Inventors: Franky So, Amin Salehi, Felix N. Castellano
  • Polymerization methods
    Patent number: 11078302
    Abstract: Disclosed herein are methods of forming (co)polymers from polymerizable compositions, the methods comprising irradiating the polymerizable compositions with light, wherein the polymerizable compositions comprise a polymerization initiator having an absorption band and exhibiting triplet-triplet annihilation up-conversion and a monomer. Also disclosed herein are methods of additive manufacturing using the methods of forming (co)polymers described herein.
