Tuning Exciton Dynamics in Asymmetric Molecular Acceptors by End-Group Modulation Enables Efficient All-Small Molecule Organic Solar Cells.
Asymmetric small-molecule acceptors have been recognized as a pivotal component in the development of organic solar cells (OSCs). Here, we report the design and synthesis of two cost-effective asymmetric molecular acceptors, SM-11 and SM-12, featuring a simple coumarin-thiophene scaffold linked to different electron-ac...
