Organic compound based on pyridine and quinoxaline and application thereof

The invention relates to an organic compound based on pyridine and quinoxaline and application thereof on an OLED device. The compound provided by the invention has relatively high glass transition temperature and molecular thermostability, and is low in absorption and high in refractive index in the field of visible light. When the organic compound is applied to a CPL layer of the OLED device, the light extraction efficiency of the OLED device can be effectively improved; the compound provided by the invention also has deep HOMO energy level and high electron mobility, can be used as a hole blocking/electron transport layer material of the OLED device, and can effectively block the transfer of holes or energy from a light-emitting layer to one side of an electron layer, thereby improvingthe recombination efficiency of the holes and electrons in the light-emitting layer, further improving the light-emitting efficiency of the OLED device and prolonging the service life of the OLED device.

Organic compound based on pyridine and benzimidazole and application of organic compound

The invention relates to an organic compound taking pyridine and benzimidazole as a core and an application of the organic compound on an OLED (organic light emitting diode) device. The compound has relatively high glass state temperature and molecular heat stability, low absorption and high refractive index in the field of visible light, and can effectively improve light extraction efficiency of the OLED device after the compound is applied to a CPL (circular-polarizing filter) layer of the OLED device. The compound further has an HOMO (highest occupied molecular orbital) energy level and high electron mobility, and can serve as a hole obstruction/electronic transmission layer material of the OLED device and effectively prevent a hole or energy from being transmitted to one side of an electronic layer from a light emitting layer, so that the combination efficiency of the hole and an electron on the light emitting layer is improved; and the light emitting efficiency and a service life of the OLED device are improved and prolonged.

Syntheses and Reactions of Some 2,3-Disubstituted Pyrazine Monoxides

The reactions of 2,3-dimethyl- (4), 2,3-diphenyl- (6), and 2-methyl-3-phenyl-pyrazine monoxides (8 and 9) with phosphoryl chloride and acetic anhydride resulted in giving monochloro- and monoacetoxy-pyrazines in almost all cases.However, the reaction of 6 with acetic anhydride afforded exceptionally a diacetoxydihydropyrazine.These products were converted further to hydroxy or dichloro derivatives.

Syntheses of Some 2-Hydroxypyrazine 1-Oxides

A series of 2-hydroxypyrazine 1-oxides were prepared from the corresponding chloropyrazines by two methods, including oxidation processes in satisfactory yields.The treatment of 2,3-diphenylpyrazine 1,4-dioxide (6) led to 2,3-dichloro-5,6-diphenylpyrazine
