The invention provides an aromatic amine derivative, and a preparation method and application thereof, which relate to the technical field of organic optoelectronic materials. The aromatic amine derivative obtained through the invention can be used for preparing an organic light-emitting device, and is particularly used as a hole-transmission material in the organic light-emitting device, so that the light-emitting efficiency and the service life of an OLED (Organic Light Emitting Diode) device can be effectively improved, and are better than those of an existing common OLED device. The invention also provides the preparation method of the aromatic amine derivative. The preparation method is simple, and the raw materials are easy to get.
The cyclodesulphurization of thio-compounds. Part 15: Synthesis of 6-substituted aminophenanthridines from some thiourea derivatives.

Several N-alkyl, aryl, and aralkyl-N'-2-biphenylthiourea derivatives have been synthesized and cyclodesulphurized into the corresponding 6-substituted aminophenanthridines. The ring closure was brought about with mercuric chloride, phosphoryl chloride or polyphosphoric acid. Phosphoryl chloride was found to be the most efficient in inducing ring closure and producing the highest yield of cyclized products. The results of study on the cyclodesulphurization reaction mechanism suggested the formation of a carbodiimide intermediate and identified some of the organic mercurials involved in the various stages of the reaction.
