Abstract

Organic semiconductors have the potential to contribute to sustainable electronics manufacture due to their ability to be processed from low-energy solution-processing methods. However, improvements must be made in the lifetime of such devices. PEDOT:PSS, a popular hole transport material, is acidic, which causes degradation in devices over time. Therefore, a replacement is needed to allow for longer lasting organic semiconductor devices. We have previously reported BEDOTPy, a non-acidic, molecular material that could be used to improve the device lifetime of OLEDs. In this work we explore how molecular engineering of BEDOTPy, by modifying the molecule’s side chain, affects the physical properties that are important to device performance and lifetime.
