    • An electroluminescent device comprising a luminescent layer is provided. The luminescent layer comprises a mixed monomolecular film of at least one electroluminescent organic compound and at least one organic compound which is different in electro-negativity from said organic compound or a built-up film thereof.The luminescent layer may be of a double-layer structure wherein a first layer of the luminescent layer comprises a mixed monomolecular film of an electroluminescent organic compound which is electron-acceptable relative to a second layer of the luminescent layer and an organic compound which is electron-acceptable relative to said compound or a built-up film thereof, and the second layer comprises a mixed monomolecular film of an electroluminescent organic compound which is electron-donative relative to the first layer and an organic compound which is electron-donative relative to said compound or a built-up film thereof.
    • 提供了包括发光层的电致发光器件。 发光层包括至少一种电致发光有机化合物的混合单分子膜和至少一种与所述有机化合物的电负性或其积聚膜不同的有机化合物。 发光层可以是双层结构,其中发光层的第一层包括相对于发光层的第二层是电子可接受的电致发光有机化合物的混合单分子膜和作为电子的有机化合物 - 相对于所述化合物或其组合膜是可接受的,并且第二层包含相对于第一层为电子发射的电致发光有机化合物的混合单分子膜和相对于所述第一层为电子给体的有机化合物 化合物或其组合膜。
