文摘
- •
A series of NPh2-modified Ir(III) complexes Ir1-Ir4 have been synthesized.
- •
The luminescent lifetimes of Ir1-Ir4 are prolonged due to the diphenylamino group.
- •
The photostabilities of Ir1-Ir4 are enhanced efficiently over Ir(ppy)2(acac).
- •
Ir1-Ir4 demonstrated excellent oxygen sensitivity with I0/I100 > 14.
