Provided is a stacked organic electroluminescence device. At least one light-emitting unit of the stacked organic electroluminescent device includes an organic layer including a specific combination of a P-type material with a deep LUMO energy level and a hole transporting material with a deep HOMO energy level. Meanwhile, a P-type material is used as the buffer layer of the charge generation layer between the light-emitting units. The device can offer better device performance and more simplified fabrication process. Further provided is a display assembly including the device.

Provided are a method of preparing a malononitrile oxime ether compound and an intermediate compound. The malononitrile oxime ether compound has a structure as shown in formula (VII), wherein W is selected from aryl or heteroaryl. The preparation method comprises steps: reacting a first raw material with a second raw material in the presence of a first solvent and a catalyst to obtain the intermediate compound, wherein the first raw material has a structure as shown in formula (IV), and the second raw material has a structure as shown in formula (V); and subjecting the intermediate compound as shown in formula (VI), and, a dehyclrant to a dehydrantion reaction in the presence of a second solvent to obtain the malononitrile oxime ether compound. In the preparation process for the intermediate, a cheaper cyanoacetamide is used as a raw material, the reaction conditions are mild. Moreover, the yield of the intermediate compound is high and the cost of the process is low. Furthermore, the required malononitrile oxime ether compound, is obtained only through one-step dehydration reaction. Using the preparation method, is advantageous for improving the yield of malononitrile oxime ethers and reducing the cost of the process.
