Abstract

Chlorinated solvents are commonly used to process organic semiconductor devices but have several negative environmental impacts. The choice of processing solvent significantly affects the layer microstructure and device performance, so replacing chlorinated solvents is non-trivial. Herein, we investigate the microstructural and electron-transporting properties of small-molecule non-fullerene acceptor (NFA) films and transistors processed from various non-chlorinated solvents. We show that the ensuing NFA transistors exhibit improved layer morphology, crystallinity, and electron mobility superior to those processed from chlorinated solvents. Our work highlights using non-chlorinated solvents to optimise charge transport in organic semiconductors and their devices while mitigating adverse environmental effects.
