  • Publication number: 20240116914
    Abstract: It is an object of the present invention to provide a compound for a capping layer that has a high refractive index and a low extinction coefficient in a range of 450 nm to 750 nm to improve the light extraction efficiency of an organic EL element. The present invention has focused on the fact that compounds having a benzene skeleton at the center thereof are excellent in stability and also durability in the form of a thin film, and that the refractive index thereof can be improved by modifying the molecular structure, and thus, molecules have been designed. Provided is a compound represented by a general formula (1), and an organic EL element with excellent luminance efficiency is obtained by using that compound as a constituent material of a capping layer.
