Core and π‐Bridge Engineering to Deconstruct Y6‐Series into Modular Non‐Fused Acceptors: DFT‐Guided Structure‐Property Map for Organic Solar Cells

Advanced Electronic Materials, EarlyView.
The rigid fused backbone of Y6‐series acceptors is deconstructed into a modular, non‐fused A‐π‐A′‐π‐A architecture. Comprehensive quantum chemical simulations reveal that strategic core and π‐bridge engineering preserves strong near‐infrared light‐harvesting and enhances intramolecular charge‐transfer character.
