原始摘要（英文原文）· Original abstract A stepwise trifluoromethyl substitution strategy is developed for the structural modification of small-molecule acceptors. The device based on –C(CF 3 ) 3 functionalized CHE-9F achieves an efficiency of 20.30%. 读原文 · Read the paper ↗ Synergistic steric–dipole modulation <i>via</i> stepwise trifluoromethyl substitution enables active-layer hierarchical assembly and >20% power conversion efficiency in organic photovoltaic devices — 科研速览 Science Skim
