Positionally heterogeneous non-fully conjugated dimeric acceptors with unilateral conjugated π-bridges enable highly efficient and stable organic solar cells

In this study, two non-fully conjugated dimeric acceptors, DYTC6T-V-out and DYTC6T-V-in, were designed and synthesized via a unilateral conjugated π-bridge strategy, introducing positional isomerism at the π-bridge site.
