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 is a modifier of a four-membered ring derivative, a preparation method and application thereof. In particular, provided is a compound represented by the general formula (IX-A), a preparation method thereof, a pharmaceutical composition containing the compound, and a use thereof as a G protein-coupled receptor modulator in the treatment or prevention of central nervous system diseases and/or mental diseases. The definition of each substituents in the general formula (IX-A) is same as the definition in the specification.
