ORGANIC LUMINESCENT COMPOUND EXCELLENT IN LUMINESCENT EFFICIENCY IN HIGH DOPING CONCENTRATION, PREPARATION METHOD THEREOF AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

PURPOSE: An organic luminescent compound is provided, which is excellent in electroconductivity, brightness, color purity, and luminescent efficiency in a high doping concentration. And also the organic electroluminescent device using the organic luminescent compound is provided. CONSTITUTION: The organic luminescent compound represented by the formula(1) is produced by a process containing the steps of: reacting a compound represented by the formula(6) and a compound represented by the formula(7) in a THF solution of sodium bis(trimethylsilyl)amide(NaN(TMS)2); performing cyclization of the resultant by using a concentrated sulfuric acid; reacting the resultant with dicyano malonate; reacting the resultant with julilodyl aldehyde in the presence of piperidine. And the organic electroluminescent device contains the organic luminescent compound as a red light emitting material. In the formulas, R1 is a C6-C20 fused ring compound.
