What is the significance of using anisole as a solvent in the processing of semiconducting polymers?

Label:chem

Topic
Most high-performing semiconducting polymers rely on toxic halogenated solvents, which pose serious health and environmental concerns. Developing polymers that can be processed using green solvents is essential for sustainable manufacturing.
Answer
Anisole is considered a green solvent due to its low toxicity and environmental impact. The use of anisole allows for the processing of semiconducting polymers like PTQBT-T without compromising performance. PTQBT-T films spuncast from anisole exhibit a hole mobility of 2.30 cm²V⁻¹s⁻¹, which is a record high for green solvent-processable semiconducting polymers via spin-coating. This demonstrates that anisole can be used to achieve high-performance organic electronic devices while maintaining environmental sustainability.
