- Phosphoryl substituted Fluoranthene derivatives and organic electroluminescent device including the same
-
Provided are phosphoryl group bonded fluoranthene derivatives represented by chemical formula 1. In chemical formula 1, the definition of each substituent group is the same as described in the specification. The fluoranthene derivatives have excellent current density and durability in comparison to a conventional material, and can be used to an organic electroluminescent device, thereby lowering the driving voltage and improving luminous efficiency while extending the lifespan.

- NOVEL ORGANIC ELECTROLUMINESCENT COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME
-
The present invention relates to a novel compound and an organic electroluminescent device containing the same. Since the compounds according to the present invention have high efficiency in transporting electrons, crystallization could be prevented when manufacturing the device, and since they are adaptable in the formation of the layers, the current characteristic of the device is improved, and finally they can manufacture an organic electroluminescent device having lowered driving voltage, advanced power efficiency, and improved light emitting efficiency and lifetime characteristic compared with devices comprising the conventional materials.

- NOVEL COMPOUNDS FOR ORGANIC ELECTRONIC MATERIAL AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME
-
Provided are novel compounds for organic electronic material and an organic electroluminescent device using the same. Because the compounds for organic electronic material according to the present invention are highly efficient at transporting electrons, crystallization is prevented when manufacturing a device and current properties of the device are improved due to favorably formed layers. Accordingly, OLED devices having improved power efficiency as well as reduced operating voltage can be manufactured.

- Metal- and chemical-oxidant-free c-h/c-h cross-coupling of aromatic compounds: The use of radical-cation pools
-
Pool and couple: A method for oxidative C-H/C-H cross-coupling has been developed using "radical-cation pools". Aromatic compounds react with aryl radical cations, which are generated and accumulated by low-temperature electrolysis (see scheme). This method avoids both the nonselective oxidation of substrates and oxidation of products and effects the C-H/C-H cross-coupling of aromatic compounds without metal complexes and chemical oxidants.
