具有二维柱状中间相的盘状聚芳族液晶因其长程有序自组织和高载流子传输能力而被积极研究作为一维有机半导体的潜在用途。然而，最近发现报道较少的含向列相盘状材料也具有工业重要性。在这种情况下，设计了高度共轭的芴桥联苯并菲三单元组，其目的是诱导室温向列相。在我们的方法中，改变中心芴单元所具有的烷基链的长度，以限制空间填充，调节分子间π-π相互作用，并控制分子三联体堆积成柱的趋势，以及随后以特定方式聚集柱的趋势。这个策略是成功的，除了自然预期的二维柱状中间相之外，大多数三元组还表现出更多难以捉摸的......
Discotic polyaromatic liquid crystals exhibiting 2D columnar mesophases are actively investigated for their potential utilization as one-dimensional organic semiconductors, due essentially to their long-range order self-organization and high charge carrier transport ability. The much less reported nematic-containing discotic materials have however been recently found to be of industrial importance too. In this context, highly conjugated fluorene-bridged triphenylene triads have been designed with the aim of inducing room temperature nematic phases. In our approach, the length of the alkyl chains bore by the central fluorene unit was changed in order to constrain the space-filling, to modulate the intermolecular π–π interactions, and to control the tendency of the molecular triads to stack into columns, and the subsequent aggregation of the columns in specific ways. This strategy was successful, and in addition to the naturally expected two-dimensional columnar mesophases, most triads exhibit the more elus...
