  • Publication number: 20250034172
    Abstract: An organic light emitting device using a compound of the following general formula has excellent characteristics. R1 to R4 each are a hydrogen atom, a deuterium atom, an alkyl group, an aryl group, or a donor group; two or more of R1 to R4 are donor groups, and at least one thereof is a substituted ring-fused carbazol-9-yl group; X1 to X3 each are N or C(R), R is a hydrogen atom, a deuterium atom or a substituent; Ar1 and Ar2 each are an aryl group; L1 is a single bond or a linking group.

  • Publication number: 20240298538
    Abstract: A compound represented by the following general formula is an excellent light emitting material. R1 to R5 each represent a hydrogen atom, a deuterium atom, or a substituent other than a cyano group, but one or more of R1 to R5 is an aryl group or a pyridyl group, two or more of R1 to R5 are donor groups, and one or more of them are a substituted ring-fused indol-1-yl group (the number of rings constituting the fused ring is 4 or more).

  • Patent number: 8640716
    Abstract: An object of the present invention is to provide a cosmetic applicator in which a surface of a wide, flat spatula projecting from a shaft includes an application portion formed from flock but the flock does not peel due to friction with a wiping part even after repeated use. In a cosmetic applicator in which electrostatic flocking is implemented on a surface of a spatula formed by forming an application portion in a flat plate shape, forming a root portion in a columnar shape attached to a shaft, and gradually deforming the columnar root portion and the flat application portion from the columnar shape into the plate shape, a projecting portion that projects outward beyond an outer diameter of the shaft is formed on the spatula between the root portion and the application portion, and a part not subjected to flocking is provided between the projecting portion and the root portion.

  • Patent number: 8579533
    Abstract: Provided is a container for a viscous cosmetic such that even when the viscous cosmetic makes contact with the applicator comprised of silicone resin there is little swelling of said applicator and the quality of the viscous cosmetic container is well maintained. An applicator made of silicone resin inside which is formed a flow-way which can communicate with a housing for internally housing a viscous cosmetic is connected to one end of the housing. A distributing port which communicates with the flow-way is formed in the applying-surface of the applicator and the viscous cosmetic within the housing can be discharged outward from the distributing port. The degree of swelling of the applicator produced by contact with the viscous cosmetic is set to from 0 wt % to 5.
