  • Hole transport polymeric compound and polymer light emitting diode using the same
    Patent number: 9373791
    Abstract: A hole transport polymeric compound and a polymer light emitting diode using the same. The hole transport polymeric compound includes a hole transport material, a thermal cross-linking agent containing an ethynyl group, and a compound represented by [Formula 1], and can be applied to a polymer light emitting diode. In addition, the hole transport polymeric compound has excellent hole transport capabilities and has stability in solvents so as to be insoluble in a solvent used upon stacking other organic layers and blocking electrons well.

  • Film member, film target for laser-driven ion acceleration, and manufacturing methods thereof
    Patent number: 8907299
    Abstract: The present disclosure provides a method of manufacturing film member for laser-driven ion acceleration, a film target, and a method of manufacturing the same, so that only the film member exists at a laser focusing point on the film target, allowing repeated ion acceleration from the film member by focusing high power laser beams thereon. The method includes preparing a film member solution containing a film material to be used for laser-driven ion acceleration; forming a film member on a base substrate by using the film member solution; and separating the film member from the base substrate by dipping the base substrate having the film member formed thereon into a film parting solvent.
