Preparation and Characterization of Novel Polyfluorenes Derivatives Containing Phenanthro9,10-dimidazole Group for Deep Blue-Light-Emitting Polymers

摘要：

　　A series of novel polyfluorenes derivatives containing different ratio of phenanthro -9,10-dimidazole (PI) group on backbone are designed,synthesized and well characterized.Comparing with the class blue polymer PF,they all exhibit deep blue emission in solution and film with high PL efficiency,and show better film forming ability because of the insert of bulky substituent on PI unit by the AFM measurement.The CV results of all compounds deliver balanced carriers injection ability,and the decreased LUMO levels and improved HOMO levels are observed,which is befit of the preparation of high performance deep blue OLED.
