  • Patent number: 12075698
    Abstract: The disclosure belongs to the technical field of organic photoelectric materials, and discloses carbonyl containing organic electroluminescent materials and use thereof in OLED. The carbonyl containing organic electroluminescent materials have a structure of formula I, wherein R1 and R2 are different in Formula I, R1 and R2 are different electron-donating groups of aromatic ring derivatives; R1 is an electron-donating groups of hole transport host materials or electron-donating groups of bipolar transport host materials. The luminescent materials of the present disclosure are organic electroluminescent materials based on derivatives of a host material and a benzoyl group. They have both AIE and delayed fluorescence characteristics with high-efficiency solid-state emission, high exciton utilization, and bipolar features.

  • Patent number: 10745516
    Abstract: Provided herein is a narrow-range polyacetylene ester compound and a preparation method. The narrow-range polyacetylene ester compound has a structural formula as represented by formula (I). The method includes: in atmospheric carbon dioxide environment, a bifunctional alkyne monomer, carbon dioxide, and a dihalide monomer perform polymerization reaction by means of a combined action of a catalyzer and alkali, dissolve the product into an organic solvent, then add same to a precipitant for precipitation, collect precipitates, and dry same to the constant weight to obtain the narrow-range polyacetylene ester compound. The reaction is carried out in atmospheric carbon dioxide atmosphere, and carbon dioxide is involved as a monomer in the formation of a polymer. The obtained narrow-range polyacetylene ester compound has good thermal stability and excellent processability. Due to introduction of an aggregation-induced emission group, some polymers show a typical aggregation-induced emission performance.
