π-conjugated, electron-neutral (i.e., neither highly electron-rich nor highly electron-deficient) buildingblocks represent a major goal for polymericsemiconductors, however their realization presents synthetic challenges. Here we report that an easily accessible (minimal synthetic steps), electron-neutral thienyl-vinylene (TVT)-based buildingblock having weak intramolecular S···O "conformationallocks" affords
了解分子/大分子结构与有机薄膜晶体管 (TFT) 性能之间的关系对于实现下一代高性能有机电子产品至关重要。在这方面,平面 π 共轭、电子中性(即,既不是高度富电子也不是高度缺电子)构建块代表了聚合物半导体的主要目标,但是它们的实现提出了合成挑战。在这里,我们报告了一种易于获得(最少的合成步骤)、基于电子中性的噻吩基 - 亚乙烯基(TVT)的具有弱分子内 S…O“构象锁”的构建块提供了一类新的稳定、结构平面的解决方案-可加工的、高迁移率的、分子和大分子半导体。在 DFT 计算的电子结构、有利的 MO 能量学、X 射线衍射衍生的分子结构、实验晶格内聚力指标和优异的 TFT 性能中,将弱 TVT 电子丰富度与超分子平面化相结合的吸引力是显而易见的。基于 TVT 的聚合物 TFT 在空气中表现出稳定的载流子迁移率高达 0.5 和 0.05 cm(2)/V·s(分别为 n 型和 p 型)。具有高电压增益
