The invention belongs to the field of photoelectric materials, and in particular relates to a blue ray organic electroluminescent material with the structural formula shown as P, wherein R is hydrogen atom or C1-C20 alkyl. The blue ray organic electroluminescent material has higher LUMO (lowest unoccupied molecular orbital) energy level and lower HOMO (highest occupied molecular orbital) energy level, is conducive to blue shift of material luminescent wavelength, and also has higher phosphorescence quantum efficiency and better dissolution properties and processing properties. The invention also provides a preparation method of the blue ray organic electroluminescent material and application of the blue ray organic electroluminescent material in organic electroluminescent devices.

Artificial low-tide elevation device for protecting islands
InactiveCN102613116ASufficient powerProtect the marine ecological environmentClimate change adaptationPisciculture and aquariaEcological environmentFishing industry in the Maldives
The invention discloses an artificial low-tide elevation device for protecting islands, which comprises an underwater artificial reef and an abovewater scientific research, observation platform, an island symbolic stone tablet. The artificial low-tide elevation device for protecting islands is characterized in that the underwater artificial reef is in the shape of a pyramid and composed of a plurality of tiers of cast blocks, the top tier is composed of rectangular cast blocks, the tiers below the top tier are composed of middle rectangular cast blocks, cubic cast blocks connected with the rectangular cast blocks, peripheral wedged cast blocks and triangularly pyramidal cast blocks on four edges, the artificial reef is fixed on a seabed foundation through 'barbed' components, and accordingly the whole artificial low-tide elevation device is more stable. The island symbolic stone tablet is organically combined with the artificial reef, so that fishery resources can be protected, ocean ecological environment can be improved, ecological environment of Chinese islands can be protected better, and completeness of the islands is protected.
