Modulating π-Spacer Architecture Directs Linear Backbone Conformation and Ordered Molecular Packing toward Efficient Organic Solar Cells

The development of high-performance polymer donors is essential for advancing non-fullerene organic solar cells (OSCs). While the triazolo[4,5-f]isoindole-5,7(2H,6H)-dione (TzDI) unit has emerged as a promising electron-withdrawing building block, its synthetic accessibility remains limited by poor atom economy, high...
