Latest Patents

Yong-Jin Pu's latest patents include an organic thin-film laminate and an organic electroluminescent element. The organic thin-film laminate aims to suppress function reduction when an intermediate layer is formed using a wet method. It features one or more organic functional layers, including a first light-emitting layer that contains a material soluble in polar solvents but insoluble in fluorinated solvents. Additionally, it has a second light-emitting layer laminated on the first, with intermediate layers comprising a non-curable material. One of these intermediate layers contains a conductive polymer that has no polymerizable group and includes a fluorinated solvent in a specific range.

The organic electroluminescent element is designed to enhance efficiency by forming a stable electron injection layer and a charge generation layer that effectively exhibits its function. This element includes at least one organic layer between a pair of electrodes, with an electron injection layer comprising a ZnO-containing layer and a charge generation layer that features an electron acceptor-containing film in contact with the cathode side.
