Abstract

The present invention provides an organic luminescent material 9-(4-aryl ethynyl phenyl) carbazoles, prepartion method and uses. The invention uses 9-(4-iodo-benzene) carbazole or derivates thereof as raw materials, under the action of tri-n-butylamine, using dual-triphenylphosphine palladium dichloride / cuprous iodide as catalyst to proceed a Sonogashira coupling reaction with the terminal aryne in tetrahydrofuran for 20 to 50 hours to obtain series of 9-(4-aryl ethynyl phenyl) carbazoles compounds. The compounds can by used as organic luminescent materials.

Description

technical field [0001] The invention belongs to the technical field of photoelectric materials. It specifically relates to a 9-(4-arylethynylphenyl) carbazole compound, a synthesis method and an application. The compound has light-emitting properties, and can be used as an organic light-emitting material in the fields of light-emitting devices, photovoltaic cells, organic light-emitting diodes, and the like. technical background [0002] Organic light-emitting diode display device (Organic light-emitting diode, OLED) will become a new generation of light source and flat panel due to its many excellent advantages such as rich colors, active light emission, small size, thin thickness, wide viewing angle, low energy consumption and fast response speed. A strong contender for the display. So far, the development of novel and highly stable carrier-transporting materials and light-emitting materials is a key factor in improving the efficiency and lifetime of organic electronic, ...
