Conformational Locking through Intramolecular F···H Interactions in Dimerized M-Series Acceptors Boosts Efficiency and Stability of Organic Solar Cells

Dimerized M-series small-molecule acceptors feature highly planar conjugated backbones, enabling ordered stacking and enhanced morphological stability. However, rotatable bonds introduced during dimerization often induce conformational disorder, undermining efficient charge generation...
