The Synthesis And Properties Of Novel Organic Electroluminescent Materials Based On Triarylamine Derivatives

In recent years,with the rapid development of network and computer technology,organic electroluminescent devices plays a more and more important role in people’s life.In organic electroluminescent devices,hole-transporting materials can overcome the barriers of carrier injection to reduce the driving voltage,realize a directional and orderly migration of carrier,and improve the device efficiency.Based on the above background,we have synthesized a series of three aromatic amine as the main structure of the hole-transporting materials,and we also tested the structure and optical physics of the compounds.In first chapter,we briefly introduced the development of organic electroluminescent materials,the structure and the luminescent principle of the organic electroluminescent devices,at the same time,we also introduces the use and common compound structure of each layer material.In second chapter,we synthesized a series of compounds which used three aromatic amine as the main structure,and estimated the structure of the compounds through ~1H NMR and the high resolution mass spectrometry.At the same time,we studied the optical physics of the compounds what we synthesized.In third chapter,on the basis of the second chapter,we synthesized three fluorene-three aromatic amine derivatives,and estimated the structure of the compounds through ~1H NMR and the high resolution mass spectrometry.
