The present invention relates to the characteristics of the light emitting transition metal complex used in the electroluminescent device, and more particularly, to the synthesis and the light emitting properties of the dinuclear iridium and the platinum complex. The organic light emitting compound according to the present invention is characterized by the following Chemical Formula 1.n n n (Formula 1)n n n n n n n n In the above formulan n n M is the central metal and is composed of the same or combination of iridium and platinum atoms. The ligands coordinated to the central metal are two phenylpyridine groups (ppy, ) And R 1 to R 6 are hydrogen and methyl, ethyl, propyl, butyl, methoxy, isopropyl, tert-butyl, phenyloxy, benzyloxy, dimethylamino and di A phenylamine no group, a pyrrolidine group, an alkane, an alkene, a phenyl group, a carboxyl group, fluorine, etc. are the same or consist of combinations. As a crosslinking agent, conjugated crosslinking agent tetrapyridophenazine (tpphz), which connects the metal of the sock end, and is capable of electron transfer, was used. In this study, the electron flow is characterized by a conjugated molecular system structure with a smooth C = N chromophore. |
