초록

We report the synthesis and electroluminescent properties of new aromatic compounds as emitting materials based on indenopyrazine, such 2,8-bis(3,5-diphenylphenyl)-6,6,12,12-tetraethyl-6,12-dihydrodiindeno[1,2-b:1',2'-e]pyrazine (DPP-EPY) and 2,8-bis(3',5'-diphenylbiphenyl-4-yl)-6,6,12,12-tetraethyl-6,12-dihydrodiindeno[1,2-b:1',2'-e]pyrazine (DPBPEPY). DPP-EPY showed high thermal stability, narrow FWHM of 46 nm, luminous efficiency of 1.04 cd/A at current density of 10 mA/$cm^2$ and CIE coordinate of (0.161, 0.104).
