摘要

设计并合成了含羟基配体8-苯并噻唑基2-萘酚(HNBT)

并以其为辅助配体、2-苯基吡啶(ppy)为第一配体合成了红色磷光铱配合物Ir(ppy)

(NBT)。采用真空蒸镀的方法

以Ir(ppy)

(NBT)为发光中心制备了红色有机电致磷光器件

详细研究了配合物Ir(ppy)

(NBT)的热稳定性、光物理与电致发光性能。值得注意的是

配合物Ir(ppy)

(NBT)的发射谱图近似于高斯形状

只有一个位于614 nm的发射主峰

没有肩峰出现

且半峰宽仅为65 nm;此外

基于配合物Ir(ppy)

(NBT)的最佳器件的最大亮度和效率分别是6 400 cd/m

和4.53 cd/A。

Abstract

A novel ancillary ligand (2-(1-hydroxy-naphthyl)-benzothiozolato) (HNBT) and the corresponding red emitting phosphorescent iridium(Ⅲ) complex

Ir(ppy)

(NBT) with 2-phenylphridine(ppy) as first ligand are designed and synthesized. Saturated red-emitting electrophosphorescent devices using Ir(ppy)

(NBT) as emission center are fabricated. The thermal

photophysical

and electroluminescent properties of Ir(ppy)

(NBT) are investigated in detail. It is noteworthy that the emission spectrum shape of complex Ir(ppy)

(NBT) is similar to Gauss

which has only one emission peak centralized 614 nm with a full-width at half-maximum of 65 nm. The optimized device exhibits a maximum brightness of 6 400 cd/m

and the peak current efficiency is 4.53 cd/A.
