A phosphorescent Ir complex having the following structures (I) or (II) is used as an emitter in an organic light emitting diode (OLED):
wherein X is an arbitrary monoanionic bidentate ligand; Z is an arbitrary moiety constituting a nitrogen-containing heterocyclic group; R
1
is a substituent on the nitrogen-containing heterocyclic group; m is 0 or a positive integer; R
2
and R
3
independently are H, halogen, C1-C6 alkyl, a halogen-substituted C1-C6 alkyl, C1-C6 alkoxy, phenyl C1-C6 alkyl, amino, aryl, heterocyclic aryl substituent.
一种具有以下结构(I)或(II)的发光Ir配合物被用作有机发光二极管(OLED)中的发射体:
其中,X是任意的单阴离子双齿配体;Z是任意的构成含氮杂环基团的基团;R1是氮含杂环基团上的取代基;m为0或正整数;R2和R3独立地为H、卤素、C1-C6烷基、卤素取代的C1-C6烷基、C1-C6烷氧基、苯基C1-C6烷基、氨基、芳基、杂环芳基取代基。
