摘要：

Using [Ir(iqbt)(ppy)(acac)] as the starting material, two geometrical isomers [Ir(iqbt)(ppy)(fprpz)]-a/b (1a/1b) were obtained by the acid-treatment approach. Moreover, the record device performance (both eta(EQE) (Max )of 6.28 % and almost negligible (<5 %) efficiency-roll-off) of the NIR-PLED-1b, engenders the isomeric [Ir(C"N)(C'"N ') (N''"N & tprime;)]-tris-heteroleptic Ir(III)-complexes a new platform to high-performance NIR-PLEDs.
