  • Publication number: 20240130219
    Abstract: Provided is an organic electroluminescent device and an application thereof. The organic electroluminescent device includes a metal complex having a substituent A capable of reducing a maximum capacitance in the device, and the metal complex can be used as an emissive material in an emissive layer of the electroluminescent device. The device including a metal complex having the substituent A can obtain a decrease in the maximum capacitance of the device, thereby improving the response time and refresh frequency of an OLED display device at a low grayscale. In another aspect, the substituent A can cause a decrease in the maximum capacitance of the device, and the device prepared with the metal complex including the substituent A can still maintain excellent device performance compared with the devices prepared with the metal complexes that do not include the substituent A. Further provided is an electronic assembly including the organic electroluminescent device.

  • Publication number: 20220403127
    Abstract: Disclosed herein is a composite material suitable for inhibiting biofilm growth, the composite material comprising a substrate material and a random copolymeric material covalently bonded to a surface of the substrate material. The random copolymer contains repeating units having at least one functional group bearing a cationic charge and repeating units having at least one functional group bearing an anionic charge, where the repeating units are derived from compatible monomers that belong to different monomer classes having differing polymerisation kinetics. Specifically, the random copolymeric material is poly(AMPTMA-ran-SPM), wherein AMPTMA is (3-acrylamidopropyl) trimethylammonium chloride and SPM is 3-sulfopropyl methacrylate potassium. Also disclosed are methods of manufacturing said material and applications thereof.
