Organic electroluminescent host material and application thereof in organic electroluminescent device

The invention relates to an organic electroluminescent host material. In an organic light-emitting device, in order to reduce the problems of exciton quenching, efficiency roll-off, device service life shortening and the like caused by too high exciton concentration in a light-emitting layer, a light-emitting layer structure generally adopts a host-guest doping mode. Aiming at different luminescent material systems/luminescent mechanisms, the requirements on the basic performance of the host material are different. The invention designs an organic electroluminescent host material based on a 3,3'-dicarbazole unit and a 9,9'-diphenyl fluorene steric hindrance group end capping. The dicarbazole unit endows the material with good carrier transport performance, and end group steric hindrance can effectively inhibit local aggregation of a light-emitting guest. According to different luminescent material systems, the polarity and size of molecules are adjusted by changing the difference of carbazole N-substituent (R), so that the comprehensive optimization of the device performance is realized.

Method for synthesizing N-aryl carbazole compound by catalyzing reaction of carbazole with aryl hydrazine by using transition metal

The invention relates to a method for synthesizing an N-aryl carbazole compound by catalyzing reaction of carbazole with aryl hydrazine through transition metal. According to the method, a transitionmetal salt is used as a catalyst, a carbazole compound and an aryl hydrazine compound are used as reaction substrates, the reaction substrates and an alkali compound are added into a solvent for a reaction for a certain period of time to obtain a reaction solution, and the reaction solution is separated and purified to obtain the N-aryl carbazole compound. According to the method, low-boiling-point acetonitrile is used as a reaction solvent, so post-reaction treatment is easy to carry out; oxygen in the air serves as an oxidizing agent, so reaction conditions are environmentally friendly and safe, cost is low, and excessive oxidation is avoided; an aryl hydrazine compound is used as an arylation reagent, and reaction byproducts only comprise water and nitrogen, so the method is environment-friendly and pollution-free; the transition metal salt is used as the catalyst, the activity of the transition metal salt is high, the use of equivalent noble metals is avoided, and synthesis cost isreduced; and generally speaking, the synthesis method is friendly to environment, simple in process, good in reaction selectivity and high in yield, and has a relatively strong industrial applicationprospect.
