基于苝二酰亚胺的供体-受体共聚低聚物在塑料电子产品中特别有吸引力,因为它们具有独特的电活性特性,可以通过适当的化学工程进行调整。在此,合成了一类具有二元结构 (AD) 或三元结构 (DAD 和 ADA) 的新型共聚寡聚体,以了解共聚寡聚体分子结构与自组装形成的结构之间的相关性。薄膜。受体嵌段 A 是苝四羧基二亚胺 (PDI),而供体嵌段 D 由噻吩、芴和 2,1,3-苯并噻二唑衍生物的组合制成。D 和 A 嵌段通过短而灵活的乙烯间隔物连接,以简化薄膜中的自组装。使用小而宽的 X 射线衍射和透射电子显微镜进行的结构研究表明 AD 和 ADA 薄片由具有重叠和强 π 堆积 PDI 单元的双层共聚低聚物组成,因为 PDI 的截面积约为施主块。这些结构模型允许合理化 DAD 共聚低聚物的组织缺失,从而为基于 PDI 的二元组和三元组的设计绘制一般规则,这些二元组和三元组具有在有机电子产品中使用的适当自组装特性。

A series of novel star-shaped small molecules with triphenylamine as the core, oligothiophene as the spacer and 1,8-naphthalimide as the electron withdrawing end-group were synthesized and used as donor materials for solution-processed organic solar cells. Direct arylation and Suzuki cross-coupling were used to synthesize the key intermediates and star-shaped molecules. The star-shaped molecules showed
A process including:
creating a composition composed of a liquid and a self-organizable polymer at least partially dissolved in the liquid, resulting in dissolved polymer molecules;
reducing the solubility of the dissolved polymer molecules to induce formation of structurally ordered polymer aggregates in the composition;
depositing a layer of the composition including the structurally ordered polymer aggregates; and
drying at least partially the layer to result in a structurally ordered layer, wherein the structurally ordered layer is part of an electronic device and the structurally ordered layer exhibits increased charge transport capability.
A thin film transistor wherein the semiconductor layer is prepared by a process including:
creating a composition comprising a liquid and a self-organizable polymer at least partially dissolved in the liquid, resulting in dissolved polymer molecules;
reducing the solubility of the dissolved polymer molecules to induce formation of structurally ordered polymer aggregates in the composition;
depositing a layer of the composition including the structurally ordered polymer aggregates; and
drying at least partially the layer resulting in the structurally ordered semiconductor layer, wherein the structural order of the semiconductor layer increases the charge transport capability of the semiconductor layer.
