Digitally Printed Molecularly Oriented Organic Semiconductors for Optoelectronic Devices

该项目的主要目标是通过喷墨打印对有机半导体材料的分子取向进行按需控制。通过在油墨配方中使用结晶性添加剂作为干燥过程中的模板，我们将能够独立于基材沉积自组织取向薄膜。因此，我们将能够访问和设计增强薄膜光电子器件功能的材料特性，如场效应晶体管和偏振敏感光电探测器。最重要的是，由于数字制造过程的性质，我们预计将对未来复杂电子系统的制造产生影响，这些系统包括定制的组件，可以自由地设计和放置在任意基板上。

The main objective of the project is the on-demand control of the molecular orientation of organic semiconducting materials by inkjet printing. By using a crystallizable additive in the ink formulation that serves as a template during the drying process, we will enable the substrate independent deposition of self-organized oriented films. Consequently, we will be able to access and design material properties enhancing the functionality of thin film optoelectronic devices such as field-effect transistors and polarization sensitive photodetectors. Most importantly, due to the nature of the digital fabrication process we expect to have an impact on the fabrication of future complex electronic systems comprising of tailored components with freedom of design and placement on arbitrary substrates.
