Advanced polymer inks for solution-based OLED manufacturing

Abstract

This thesis introduces a key step towards the industrial manufacturing of Organic Light Emitting Diodes (OLED) used in display technologies and solid-state lighting. Thin polymer films for OLED devices can be deposited by resource efficient, precise ink-jet printing and through post-printing irradiation to form resistant networks suitable for multi-layer fabrication. Tailored polymers were designed to incorporate all relevant components such as the fluorescence emitter, the photocrosslinkers as well as the host material. The functional polymer’s composition and the light-driven crosslinking conditions were optimised.
