铱错合物及使用其之有机电场发光元件;IRIDIUM COMPLEX AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

本发明系提供一种新的铱错合物及使用其之有机电场发光元件。铱错合物包含铱原子，及与其配位之以下述式(L 1 )所示之第1配位子；(式中，附*的原子为配位至铱的配位原子，R 1 为拉电子取代基，R 2 至R 6 分别为取代基，m为1至3，n为0至4，p为0至4，q为1至3，p+q≦5，r为0至4，s为1至3，r+s≦5，t及u分别为0至4)。;There are provided a novel iridium complex and an organic electroluminescent device using the same. The iridium complex includes an Ir atom and a first ligand which coordinates to the Ir atom, the first ligand represented by a formula (L 1 ): where: an atom indicated by an asterisk is a coordinating atom which coordinates to the Ir; R 1 is an electron-withdrawing substituent; each of R 2 to R 6 is a substituent; m is 1 to 3; n is 0 to 4; p is 0 to 4; q is 1 to 3; p+q5; r is 0 to 4; s is 1 to 3; r+s5; and each of t and u is 0 to 4.
