中文摘要：

为了研究盘状液晶中载流子的传输性能,选取了一种易于合成的苯并菲衍生物,即2-正丁酯基-3,6,7,10,11-五丁氧基苯并菲进行研究。通过基本的研究手段包括核磁氢谱、傅里叶红外光谱、示差扫描量热法及偏光显微镜发现其表现出明显的六方柱状相的特征,并通过深入的X射线粉末衍射图谱可以看出,在广角区域有明显的分裂双峰,可以确定这种化合物为六方柱状塑晶相。为了研究其载流子的传输性能,采用渡越时间法测量了它的空穴迁移率为7.56×10^-3cm^2/vs,结果表明：柱状塑晶相比普通柱状相的迁移率要高出一个数量级,有利于其在导电器件中的应用,比如在OLED和OPV等领域。

英文摘要：

In order to study the carrier transport characteristics of discotic liquid crystal,this paper chooses easy synthesis of triphenylene derivatives,namely 2-butanoate-3,6,7,10,11-pentabutoxytriphenylene. Through the study of basic methods including1 HNMR and FT-IR spectroscopy,differential scanning calorimetry and polarized light microscopy,it shows hexagonal columnar phase characteristics,and through X ray powder diffraction pattern can be seen that the peak is split into two peaks which is a typical characteristic of hexagonal columnar plastic phase. In order to study the carrier transport characteristics,time-of-flight method is used and the result shows that： compared with ordinary columnar phase,mobility of plastic phase is one magnitude higher which is about 7. 56 × 10^-3cm^2/vs. It shows that this compound can be further applied in conductive devices,such as OLED and OPV.
