Abstract

The invention relates to a multi-nitrogen heterocyclic compound as well as a preparation method and an application thereof. The multi-nitrogen heterocyclic compound takes imidazo triazine with a triazine structure or 7-aza-phenalene as a matrix, and a plurality of isothiocyanate groups are introduced through chemical modification. The compound provided by the invention is high in thermal stability and glass transition temperature, and is respectively used as an electron transmitting material, a cavity transmitting material and a cavity injection material of an organic electroluminescence device for obtaining electroluminescence with very high color purity and efficiency.

Description

technical field [0001] The invention relates to a polynitrogen heterocyclic compound and its preparation method and application, belonging to the technical field of organic photoelectric materials. Background technique [0002] The so-called "organic luminescence" phenomenon (organic electroluminescence) generally refers to the conversion of electrical energy into light energy by organic substances. In particular, when an organic film is provided between the anode and the cathode and a potential is applied between the two electrodes, holes and electrons are respectively injected into the organic film from the anode and the cathode. The above-mentioned injected holes and electrons form excitons when they recombine. Further, light is emitted when the excitons drop to the ground state. [0003] In addition to the above-mentioned organic light-emitting mechanism in which light is emitted by the recombination of charges injected from both poles, there is another light-emitting ...
