Organic semiconductors have left their mark on numerous applications, such as organic photovoltaics (OPV), organic light-emitting diodes (OLED) and organic field-effect transistors (OFET). Moreover, despite steady performance increases, controlling the crystallisation behaviour of organic semiconductors remains challenging. This project focusses on the synthesis of organic semiconductors with permanent dipole moments and to subsequently control their crystallisation using a vapour-guided deposition. This novel deposition method encourages soft matter self-assembly to gain control over material patterning, alignment and resolution. Our approach will make it possible to study the crystallisation dynamics of organic semiconductors under non-equilibrium conditions. We will also be able to control the molecule alignment using an environmentally benign, contactless method to initiate crystallisation and pattern the organic semiconductors. Besides the numerous applications in plastic electronics, the research conducted as part of this project fits well within the EPSRC remit of new materials for energy applications, while at the same time providing new insights into the processing of polymer materials, and the related fluid dynamics.

有机半导体已经在许多应用中留下了它们的印记，例如有机光致发光器件（OPV）、有机发光二极管（OLED）和有机场效应晶体管（OFET）。此外，尽管性能稳步提高，但控制有机半导体的结晶行为仍然具有挑战性。该项目的重点是合成具有永久偶极矩的有机半导体，并随后使用气相引导沉积控制其结晶。这种新的沉积方法鼓励软物质自组装，以获得对材料图案化，对准和分辨率的控制。我们的方法将有可能研究非平衡条件下的有机半导体的结晶动力学。我们还将能够使用环境友好的非接触式方法来控制分子排列，以启动结晶和图案化有机半导体。除了在塑料电子产品中的众多应用外，作为该项目一部分进行的研究非常适合EPSRC能源应用新材料的范围，同时为聚合物材料的加工和相关的流体动力学提供了新的见解。
