Paragraph 0051-0053, (2019/02/26)
The invention relates to the technical field of organic luminescent materials, in particular to an organic luminous compound as well as a preparation method thereof and an organic electroluminescent device containing the same. The organic luminous compound is a class of compounds which is high in thermal stability and excellent in luminous efficiency and is formed by combining an acridine functional group having high electron hole transport efficiency with triarylamine excellent in hole transporting property; the introduction of different substituents can change the electronic transition, so that a luminous peak position can be adjusted; and a red light device made of the material provided by the invention can meet the needs of industrial production. The preparation method of the organic luminous compound, provided by the invention, is simple in preparation and suitable for industrial production; and the compound with superior performance can be obtained by adjusting the usage ratio ofreactants, reaction time and temperature. The organic luminous device provided by the invention has excellent luminous efficiency, brightness, resolution, and is long in service life.

Because N-arylation of isatin only worked with iodoferrocene (and in low yield), we employed N-arylation of 2-aminophenones and subsequent oxidative cyclization to access various N-arylated isatins. In the course of this work, we observed that N-arylation using 2-iodofuran, 2-iodobenzofuran and 2-iodobenzothiophene did not lead to the expected derivatives, but to (benzo)furo- and (benzo)thieno[2,3-b]quinolines. Separate cyclization was also performed under acidic conditions on 2-(arylamino)phenones in order to obtain acridines and related compounds. Most of the synthesized compounds were screened for their antiproliferative activity in A2058 melanoma cells, and against a panel of disease-relevant kinases such as mammalian CDK5/p25, PIM1, CLK1, DYRK1A, GSK3α/β Haspin and leishmanial CK1. The biological results are reported.

An efficient aminocyanation by the direct addition of aryl cyanamides to arynes is described, enabling incorporation of highly useful amino and cyano groups synchronously via cleavage of inert N-CN bonds, affording synthetically useful 1,2-bifunctional aminobenzonitriles. The postsynthetic functionalization of the aminocyanation products allows diverse formation of synthetically important derivatives such as drug molecule Ponstan and fused heterocycles.
