Abstract: Organic light-emitting diodes (OLEDs) offer potentially cost effective and energy efficient alternatives to their inorganic counterparts. Superior mechanical flexibility and relaxed processing conditions have allowed OLEDs to become widespread in displays and mobile devices. Next generation OLEDs are emerging, which include flexible white OLED lighting and biodegradable electronics. These applications have practical implications for reducing energy consumption and electronic waste as electronics have become ubiquitous. In this thesis, we explore two emerging areas of research in which OLEDs can be used to meet the increasing energy demands. First, we demonstrate a practical method to increase luminous efficacy of white OLEDs. This involves developing a process that spontaneously forms micro- and nano- pores in an optically transparent and high-index plastic. The porous polymer films are optimized to enable broadband outcoupling from white OLEDs. Second, we introduce the properties of low ceiling temperature polymers and their potential as plastics with high recyclability. By incorporating photocatalysts in the polymer and integrating an OLED directly atop, we demonstrate a proof-of-concept device that can realize room-temperature depolymerization reactions.
