Phytol-derived alkyl side chains forπ-conjugated semiconducting polymers

摘要

The solution-processability of π-conjugated semiconducting polymers is regarded as an important characteristic for the potential application in large-area printed flexible electron devices that distinguishes them from inorganic semiconductors. In fact, the solubility of semiconducting polymers largely relies on alkyl side chains and side chains meanwhile have a significant impact on interchain packing, molecular orientation, and polymer morphology in films, which are features that are known to affect device performance.
