- Abstract
In this study, we synthesized polynorbornene (PNB) dicarboximides substituted by monochlorophenyl group (PMCPhNDI) and dichlorophenyl group (PDCPhNDI) via ring-opening polymerization using a ruthenium catalyst and investigated their thermal, mechanical, and optical properties. We also discussed the performance and application of the functionalized PNB dicarboximide films as flexible substrates for organic light-emitting devices (OLEDs). The polymer films exhibited good optical transparency with an average transmittance of around 97% in the visible light region and good thermal stability with a 5% degradation temperature of >440°C. The polymers were applied for flexible displays, which were coated on indium tin oxide (ITO) thin films using a radio-frequency planar magnetron sputtering system with changing the deposition substrate temperatures. A flexible OLED that was fabricated on the ITO-grown polymer substrates exhibited a performance as comparable to the corresponding ITO-grown glass substrates. Copyright © 2012 John Wiley & Sons, Ltd.
