    摘要： The present invention relates to an organic luminescent material/clay nanocomposite with improved luminescent efficiency and stability, which is prepared by blending an organic luminescent material with a nanoclay, and an electroluminescent device employing the same. The electroluminescent device of the invention comprises: a transparent substrate; a semitransparent electrode deposited on the transparent substrate; a clay nanocomposite emissive layer spin-coated with an organic EL material/clay nanocomposite, positioned on the semitransparent electrode; and, a metal electrode deposited on the clay nanocomposite emissive layer. Since the electroluminescent device of the invention provides improved luminescent efficiency and stability, it can be practically applied to the development of organic semi-conductor.

    摘要： The present invention provides ionomer-type emissive polymer whose heat-stability is improved by the formation of ionic cross-link, and electroluminescent device employing the same as an emissive layer. The ionomer-type emissive polymer is characterized by an ionomeric conformation, which has a backbone in a conjugate, non-conjugate or conjugate/non-conjugate multi-block conformation with or without a side chain in a conjugate or non-conjugate conformation, and 0.1 to 15% (mol/mol) of ions bound to the backbone or side chain of the emissive polymer with or without linker. The electroluminescent diode employing ionomer-type emissive polymer can be applied to the preparation of long-life and electricity-saving electroluminescent display device since it can luminesce at low voltage due to its ionomeric conformation and have higher heat-stability than the conventional ones.

    摘要： A dendritic molecule represented by Formula 3: where Pc is metal phthalocyanine represented by Formula 2: where M is a core metal of the dendritic molecule; n is an integer in the range of 1 to 50; each of the Xs is a bivalent linking group independently selected from the group consisting of O, S, CH2, CO, SO2 and NHCO; and each of the Rs is independently selected from the group consisting of CN, COOH, SO3H and PO3H. The dendritic molecule containing metal phthalocyanine is dissolved in an organic solvent, and thus can be used to easily form a hole injection layer or a hole transport layer using solution deposition. The hole injection layer comprising the dendritic molecule containing metal phthalocyanine has good adhesion to an electrode and improved hole injection ability. The organic light emitting diode including the hole injection layer exhibits high luminance and emitting efficiency.
