The invention belongs to the technical field of organic photoelectric materials, and discloses a blue-light organic semiconductor material based on 2,6-di-tert-butylanthracene, a preparation method and an application thereof. The organic semiconductor material based on 2,6-di-tert-butylanthracene has a specific structure such as: wherein, Ar 1 , Ar 2 As the control group, Ar 1 with Ar 2 Symmetrical or asymmetrical modifications can be made. The invention mainly adjusts the light-emitting physical properties and energy level characteristics of anthracene derivatives by connecting different modification groups on the 9 and 10 positions of anthracene. The luminescent material prepared by the present invention has efficient blue or deep blue emission in solid state; the energy level structure of the material has good control characteristics, thereby adjusting the electron / hole injection performance of the material, which is beneficial to the simplification of the device structure; all materials Both have good stability and film-forming properties, and can be formed into non-doped or doped devices by vacuum evaporation, and the device preparation process is flexible.

The invention discloses a hydraulic synchronous valve which comprises a cylinder block, a primary plunger piston, a plurality of secondary plunger pistons, springs, a first solenoid valve, a second solenoid valve, an ejector rod and an inductive switch. An oil channel is formed in the cylinder block. The secondary plunger pistons are positioned in the cylinder block. First cavities are defined bythe secondary plunger pistons and the cylinder block. The first oil cavities communicate with the oil channel. The oil channel comprises a working oil channel and an oil return channel. The first solenoid valve is connected with the working oil channel. The second solenoid valve is connected with the oil return channel. The primary plunger piston is mounted in the cylinder block. A second cavity is defined by the primary plunger piston and the cylinder block. The primary plunger piston is in contact with the secondary plunger pistons. One end of each spring is connected with the correspondingsecondary plunger piston and the other end of the spring is connected with the cylinder block. The ejector rod is connected with the primary plunger piston. The inductive switch is mounted on the cylinder block, and is matched with the ejector rod. The inductive switch is electrically connected with the first solenoid valve and the second solenoid valve. Therefore, synchronous work of a pluralityof executing components and stepped oil discharging or stepped oil feeding of the executing components can be simply achieved, the control precision is high, the cost is low, the stability is high, and the safety is high.
