The advancement in building Organic Light Emitting Diodes, has led to complexes that when deposited onto substrates, become air and moisture sensitive, requiring advanced techniques in cleaning and fabrication to ensure working devices. The focus of this research is to develop a polymer coating that is comparable to the current epoxy coverings used to elongate the lifetimes of OLED devices. The purpose of the polymer, Photo-Induced Fluorinated Polymer coating (PIFPC), is to protect the devices against reduction-oxidation reactions at the substrate and surface interfaces, while preserving the characteristics of the device before and after the curing process. The characteristics sought in this polymer are transparency, similar refractive index as glass, hydrophobic, and has the capability to hinder diffusion of molecular oxygen across the polymer-device interface. PIFPC is a cross-linked poly fluorinated methacrylate polymer, made out of a fluorinated methacrylate monomer, poly ethylene glycol diacrylate as cross-linker, and hydroxycyclohexyl phenyl ketone as photo initiator. To characterize the properties of PIFPC, analysis was performed in situ (pre-cured), as a thin film(cured), and as a cover (cured) for various bilayer OLED devices.<br/>
