Abstract

Abstract : In article number 2100316, Xiao‐Tao Hao and co‐workers investigate the stabilizing function of alloy states from the perspective of controlling the aggregation of non‐fullerene acceptors. The acceptor alloys strengthen the conformational rigidity of BTP‐4Cl to restrain the intramolecular vibrations for rapid relaxation of high‐energy excited states to stabilize BTP‐4Cl. The donor alloys optimize the fibril network microstructure of PM6 to restrict the aggregation of BTP‐4Cl.
