J52-Cl is the chlorinated derivative of the J52 polymer donor, featuring chlorine atoms on its side chains to fine-tune electronic and morphological properties. Chlorination effectively down-shifts the HOMO and LUMO energy levels, improving energy alignment for photovoltaic applications. It also influences intermolecular aggregation, enhancing polymer crystallinity and charge transport, while simultaneously tuning surface energy to optimize thin-film morphology. These structural and electronic advantages make J52-Cl a promising donor material for high-performance non-fullerene polymer solar cells, where controlled aggregation and stable film formation are critical for achieving efficient and reliable device operation.
