The present disclosure relates to an organic compound having a fused aromatic or hetero aromatic ring including a carbazole or fluorene moiety and a group having excellent charge mobility property, and a light emitting diode and a light emitting device having the organic compound. The organic compound can be applied into the light emitting diode by using solution process and has very deep HOMO energy level. When the organic compound is applied into a chare transfer layer, a HOMO energy level bandgap between the charge transfer layer and an emitting material layer is reduced so that holes and electrons can be injected into the emitting material layer in a balanced manner.
Various triarylamines can be readily prepared in excellent yields by palladium-catalyzed cross-coupling reaction of aryl halides and diarylamines. The amination reaction takes place rapidly by using the catalyst combination of Pd(OAc)2 and a bulky and electron-rich ligand. P(t-Bu)3.
The process of preparing a tertiary amine by the condensation of a mono- or di-tertiary amine and a mono- or di-iodoaryl compound. Conducting the condensation reaction in the presence of potassium hydroxide, and a copper catalyst, either in the absence of a solvent or with an inert saturated hydrocarbon solvent, in an inert atmosphere, at a temperature between from about 120.degree. C. to about 190.degree. C. for a period of time sufficient to at least substantially complete the reaction.
Provided is a sulfonic acid ester compound represented by formula (1).
