液晶性直线型共轭芳炔衍生物的合成及电致发光性质
Synthesis and Electroluminescent Properties of a Liquid Crystalline Linear Conjugated Arylacetylene Derivative
摘要
Abstract
A novel asymmetrical linear conjugated diacetylene derivative,(2-(2-(4-aminophenyl)ethynyl)-5-(4-(2-(hexyloxy)naphthalen-6-yl)buta-1,3-diynyl)phenyl)methanol, was designed and synthesized from phenylamine and arylacetylene by Sonogashira reaction.By attaching the phenylamino substituent to arylacetylene,torsional states will be formed under conditions of the absence of electron withdrawing group and an effective intramolecular charge-transfer occurs, which helps improve electro-optical conversion efficiency. Furthermore,the introduction of liquid crystal property improves the charge balance of electron and hole in device and device efficiency.Moreover,an organic light-emitting device(OLED)device using the compound as emitters was fabricated, which exhibited yellow-green emission and low turn-on voltages of 7.2 V and excellent electroluminescent stability.The maximum brightness value was 126 cd/m2.So, the diacetylene derivative is a promising materials for OLED devices.关键词
