Intermediates of deuterated aromatic compounds and methods for preparing deuterated aromatic compounds using them

摘要

To provide a method for preparing deuterated aromatic compounds, in which deuterium is converted to a high level by using intermediates of deuterated aromatic compounds, and to provide an organic electroluminescent device having excellent characteristics such as a long lifespan and luminous efficiency.SOLUTION: The intermediate of the deuterated aromatic compound of the present invention is represented by a specific chemical formula 1, and the method for preparing the deuterated aromatic compound of the present invention comprises the steps of: (1) reacting anthrone or anthraquinone represented by a specific chemical formula 2 with a deuterium source under a metal catalyst to prepare an intermediate of the deuterated aromatic compound represented by the chemical formula 1; and (2) preparing a compound represented by a specific chemical formula 3 using an intermediate of the deuterated aromatic compound of the step (1).SELECTED DRAWING: Figure 1
