从实验和理论两个方面研究了两种稠环噻吩并苯异构体（镰刀状顺式异构体和线性反式异构体）的分子结构、自组装和电荷传输性质之间的关系。在相同的自组装条件下，顺式异构体形成一维（1D）微米和纳米带，而反式异构体形成二维（2D）纳米片（均为单晶）。这些差异被归因于分子结构的微小调整引起的分子间相互作用的变化。顺式异构体单晶的场效应迁移率约为反式异构体的三分之一。异构体的不同的转移积分解释了所观察到的不同的迁移率。本研究为研究有机半导体的构型异构体自组装和电荷输运性质打开了一扇生动的窗口。
The relationships between the molecular structure, self-assembly and charge transport properties of two fused-ring thienoacene isomers, a sickle-like syn isomer and a linear anti isomer, were studied from both an experimental and a theoretical perspective. Under the same self-assembly conditions, the syn isomer formed one-dimensional (1D) micro- and nanoribbons, while the anti isomer formed two-dimensional (2D) nanoplates (all were single crystals). The differences were assigned to the change in intermolecular interactions due to the tiny tuning of the molecular structures. The field-effect mobility in the single crystals of the syn isomer was about one-third as high as that of the anti isomer. The different transfer integrals of the isomers explained the observed different mobilities. This study opens a vivid window to examine the self-assembly and charge transport properties of organic semiconductors by using configurational isomers.
