Fourfold 2,3,6,10-alkoxycarbonyl-substituted triphenylenes are synthesised in five concise steps from 4-methylcyclohexanone by selective monoformylation of 2,6,10-trimethyltriphenylene, followed by oxidation in aqueous dichromate solution. Their low symmetry leads to mesogenic self assembly in a columnar liquid-crystalline state at or near room temperature, depending on the choice of alkyl group. These
通过 2,6,10-三甲基三亚苯基选择性单甲酰化,然后在重铬酸盐水溶液中氧化,从 4-甲基环己酮通过五个简洁的步骤合成四重 2,3,6,10-烷氧基羰基取代的三亚苯基。它们的低对称性导致介晶自组装在室温或接近室温下呈柱状液晶状态,具体取决于烷基的选择。这些材料结合了有机光电电荷传输薄膜所需的几种特性:室温自组装成具有良好电荷迁移率和高粘度的结构、芳香核中的低电子密度、平滑的合成通路、光学透明度
