摘要

利用Suzuki偶合反应合成了两种新的蒽衍生物9，10-二（2-联苯基）蒽（BBPA）和9，10-二[2-（-萘基）苯基]蒽（BNPA），化合物结构通过核磁、质谱及元素分析进行了表征。量子化学计算结果显示，这两种化合物都具有非共面的分子结构，光物理性能主要决定于分子中的蒽结构单元。这两种化合物在二氯甲烷溶液中均可发射高效率的蓝光。BBPA在固态薄膜状态下的发射光谱相对其二氯甲烷溶液的发射光谱明显变宽，而BNPA的固态薄膜并未发生光谱变宽现象。分别利用化合物BBPA和BNPA作为发光层材料，制备出了非掺杂的深蓝光电致发光器件。发光层为BBPA的电致发光器件的最大外量子效率和CIE色坐标分别为2.48%和（0.16，0.09）；基于BNPA的电致发光器件的最大外量子效率为2.68%，CIE色坐标为（0.15，0.07）。所制备的这两种器件均表现出了较低的开启电压和良好的稳定性。

Abstract

Two new anthracene derivatives 9

10-bis(2-biphenyl)anthracene (BBPA) and 9

10-bis[2-(-naphthyl]phenyl]

anthracene (BNPA) were synthesized by Suzuki coupling reaction and characterized by

H NMR

mass spectrum and elemental analysis. The quantum chemistry calculations show that these compounds have non-coplanar structures and their photophysical properties are controlled by the anthracene unit. Both of these compounds exhibit high-efficiency blue emission in CH

solutions. The emission spectrum of BBPA as solid film is obviously broader than that measured from CH

solution

while the emission spectrum of BNPA as solid film does not broaden compared to that acquired from CH

solution. Two deep-blue non-doped electroluminescent devices were fabricated employing BBPA or BNPA as emitting layer. The device based on BBPA exhibits a maximum external quantum efficiency of 2.48% and CIE coordinate of (0.16

0.09). The device based on BNPA acquires a maximum external quantum efficiency of 2.68% and CIE coordinate of (0.15

0.07). In addition

both of these devices show low turn-on voltage and high stability.
