To reveal the relationships among molecular structures, self-assembly behavior and the organic electronic properties of discotic liquid crystals, 2-(neopentyloxy)-3,6,7,10,11-pentakis(pentyloxy)triphenylene (T5ON1) and 2-pivalate-3,6,7,10,11-penta-pentyloxy-triphenylene (T5EP1) have been synthesized based on hexapentyloxy-triphenylene (HAT5). Their mesomorphic properties were studied by differential
为了揭示盘状液晶2-(新戊氧基)-3,6,7,10,11-戊基(戊氧基)三亚苯基(T5ON1)和2-新戊酸酯的分子结构,自组装行为和有机电子性质之间的关系基于六戊氧基-联苯撑(HAT5)已经合成了-3,6,7,10,11-戊基戊氧基-联苯撑(T5EP1)。通过差示扫描量热法(DSC),一维广角X射线衍射(1D WAXD)和二维广角X射线衍射(2D WAXD)研究了它们的介晶性质。T5ON1和T5EP1分别显示出有序的六方柱状相和高度有序的六方柱状塑性相。令我们惊讶的是,透射电子显微镜(TEM)图像证明T5EP1的有机体系中形成了均匀分布的超晶格纳米结构。此外,-2 cm 2 V -1 s -1和3.33×10 -2 cm 2 V -1 s -1表示T5EP1是双极性电荷载流子传输材料。
