    • PURPOSE: A red-emitting material consisting of a porphyrin by utilizing the fluorescence of the porphyrin, and an organic electroluminescent device having a porphyrin-contain luminescent layer are provided. CONSTITUTION: Metalloporphyrins can be used as the porphyrin but phthalocyanine can not be used for no fluorescence of a porphyrin: the porphyrin of this invention is formula 1. The porphyrin content of the luminescent layer is 1.0 weight % or above. The luminescent layer functions as a hole or electron injection and transport layer. With the high color purity of the organic electroluminescent device, the organic electroluminescent device used as color flat emitting source or red-emitting source of display electroluminescent device gets indicative factor with high reproducibility.
    • 目的:提供通过利用卟啉的荧光由卟啉构成的红色发光材料和具有含卟啉的荧光层的有机电致发光元件。 构成:金卟啉可用作卟啉,但酞菁不能用于卟啉的荧光:本发明的卟啉为式1.发光层的卟啉含量为1.0重量%以上。 发光层用作空穴或电子注入和传输层。 有机电致发光器件的高色纯度,用作彩色发光源或显示电致发光器件的红色发光源的有机电致发光器件具有高再现性的指示性因素。
