Abstract:Developing green-solvent processable polymer hole transport materials (p-HTMs) is considered imperative for industrial-scale production. However, the introduction of a large conjugated structure into molecules that ensures strong intermolecular interactions as well as high hole mobility compromises their solubility in green solvents. Lacking solubility could result in excessive phase separation and heterogeneous thin films for p-HTMs, while it would sacrifice device performance. In order to address this trade-… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
