Compound containing spiro-xanthene fluorene and application of compound to organic light-emitting device

The invention discloses a compound containing spiro-xanthene fluorene and an application of the compound to an organic light-emitting device. The compound has a spiro-xanthene fluorene structure, so that the compound has high rigidity and the advantages that crystallization and aggregation between molecule cannot be easily formed, and the compound has good film-forming property and the like afterbeing connected with a long-chain branch structure of a carbazole derivative. A parent nucleus of the compound has double polarity, a branch chain is provided with an electron-donating group, the electron donating abilities of a branch chain group are different, so that HOMO energy levels of a material are different, and the compound can serve as different functional layer materials to be used. The compound has higher triplet-state energy levels, energy loss can be effectively blocked, and energy transfer is facilitated. The compound serves as an organic light-emitting functional layer material to be applied to an OLED (organic light-emitting diode) device, current efficiency, power efficiency and external quantum efficiency of the device are greatly improved, and the service life of the device is obviously prolonged.

Greening watering device

The invention provides a greening watering device. The greening watering device comprises a bottom plate, a guide column and a position-locking groove. The bottom plate is horizontally placed on the horizontal plane, and the tops of two side walls of the left end and the right end of the bottom plate are fixedly connected with side guard plates. The top of the edge of the rear end of the bottom plate is upwards provided with a standing plate perpendicular to the plane of the top of the bottom plate. The bottom surface of the bottom plate is horizontally provided with two installing pins with plug holes, and the right ends of the installing pins are connected to a plug embedded in the side wall of the standing plate through connecting columns. According to the greening watering device, a positioning needle and a position-locking block are installed, a positioning needle rotation shaft is inserted to the part, extending to the exterior of the inner side wall of the standing plate, of a rotation shaft, and the structure of the position-locking groove is matched with the structure of the tail end of the outer side of the positioning needle, so a water diversion pipe is positioned and fixed through the positioning needle while the rotation adjustment is performed, and the water diversion pipe can be freely rotated in a preset angle. The water diversion pipe can be used for wateringwhile the shrub layers at two sides of a road need to be irrigated.
