摘要

合成了一种具有双分子结构的锌。通过X射线单晶衍射的方法确定了它的分子结构。单晶数据如下:空间群为三斜

P-

1晶系

a=0.971 9(2)

b=1.124 8(2)

c=1.190 2(2)

; α=73.099(3)°

β=81.498(3)°

=76.476(3)°。两个分子间存在有π-π相互作用。Zn(5-MeBTZ)

具有良好的热稳定性

熔点为319 ℃。以Zn(5-MeBTZ)

为发光层

NPB为空穴传输层材料的双层结构器件的电致发光光谱有较大的半峰全宽

几乎覆盖整个可见光区域。这种宽的EL谱是由于在NPB和Zn(5-MeBTZ)

界面的激基复合物产生的。优化的OLED器件结构和性能将在以后的论文中介绍。

Abstract

Bi-molecular bis zinc was synthesized. Its molecular structure was confirmed by single-crystal X-ray diffraction. Single-crystal data are as follow: space group triclinic

P-1

;

=0.971 9(2) nm

=1.124 8(2) nm

=1.190 2(2) nm;

=73.099(3)°

=81.498(3)°

=76.476(3)°. Zn(5-MeBTZ)

has a good thermal stability. The double-layer devices was employed using Zn(5-MeBTZ)

as emitter and NPB as hole-transport material

in which Zn(5-MeBTZ)

gave rise to unusually large width in electroluminescence (EL) spectrum

covering almost the range of visible light. The broadened EL spectra were demonstrated to be originated from the exciplexes formed at the interface between NPB and Zn(5-MeBTZ)

. White OLEDs could be expected to be realized by designing of reasonable device structure.
