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.
