Abstract: The aim of this research is to incorporate the photo-reactive o-nitrobenzyl ester functional group into cationic polythiophene (PT) derivatives in poly(electrolyte)multilayer (PEM) films assembled using layer-by-layer (LbL) self-assembly. Integrating a photo-responsive moiety into the PT derivative allows for light to be used to disrupt the electrostatic interactions in the film, resulting ... read morein control over solubility of the film. The fabrication of these photo-responsive PT films is sought after in hopes of creating an organic semiconductor that is also a positive photoresist, meaning it is amenable to patterning using photochemical processes such as photolithography.read less
