Abstract: Disclosed is a compound with a benzo[1,2-b: 5,4-b'] dibenzofuran core and an application thereof in organic electroluminescent devices. The compound contains a benzo[1,2-b: 5,4-b'] dibenzofuran structure having strong rigidity. After being linked with a five-membered ring, a six-membered ring or a seven-membered ring, the compound has characteristics of showing little intermolecular crystallization and aggregation, as well as excellent film-forming properties. Due to the difference in electron-donating ability of branched-chains, the material has different HOMO energy levels that can be used for different functional layers; and the compound also has a higher triplet energy level that can effectively block energy loss and facilitate energy transfer, such that using the compound as an organic electroluminescent functional layer material in an OLED device can greatly improve the efficiency and service life of the device.

Abstract: Disclosed is a method for treating a collapsible loess foundation with vibration rod compaction, comprising the following steps: (1) construction preparation, (2) vibration point positioning, (3) vibration and liquid injection, (4) vibration sinking, (5) down-hole vibration remaining, (6) vibration lifting, (7) backfill and reverse inserting, and (8) lifting completion. During the construction, according to pre-designed vibration point spacing, a triangle or square point distribution method is adopted, and the vibration point construction is carried out in sequence until the construction of a reinforcement area is completed. The injected liquid in the vibration is industrial waste liquid and can react with components such as calcium carbonate in the loess, and thus the "softening" of a soil body is accelerated, and the vibration sinking of a vibration wing is facilitated. The time of the down-hole vibration remaining is not less than 10 s. The backfilling and reverse inserting process is carried out at least once. The range of the vibration point spacing is 1.0-1.8 m. When the collapsible loess foundation is treated by the present invention, no additional padding is required, the economic benefits are obvious, and the construction is convenient and easy.
