Chemistry is traditionally divided into organic and inorganic chemistry. Quality Control of 6-Bromoisoquinoline, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 34784-05-9
The invention relates to a to pyridine and benzimidazole as the core of the organic compound and its application on the OLED device, compounds of the invention have higher glass transition temperature and molecular thermal stability; and low absorption in the visible light field, high refractive index, when applied to the OLED device after CPL layer, can effectively improve the light extraction efficiency of the OLED device; the compounds of the invention also has deep HOMO energy and high electron mobility, can be used as the OLED device of hole blocking/electron transport layer material, can effectively prevent the hole or energy from the light-emitting layer is transmitted to the electron shell one side, thereby improving the hole and electron in the luminescent layer of the composite efficiency, OLED device to further enhance the light emitting efficiency and service life.
