摘要: A method for producing 1,4-bis(dichloromethyl)tetrafluorobenzene is disclosed, which is achieved by reacting tetrafluoroterephthaldehyde, SOCl2 and organic solvents. In the synthesis of 1,4-bis(dichloromethyl)tetrafluorobenzene by adding formamides as catalyst, there are remarkable advantages which include shortening the reaction time; simplifying the synthesizing steps and raising the yield of the product.

摘要: An iridium complex is used as a phosphorescent material in an organic electroluminescence (OEL). Use this complex as the red light guest dopant emitter of the phosphorescent material, then apply the phosphorescent material to the OEL light-emitting layer, a red light that is very close to pure red can be achieved. In addition, the iridium complex can increase the thermal stability of the OEL, due to their high conjugated structure.
