A novel isotropic fullerene-hybridized fused-ring electron acceptor, designated C-Y, has been synthesized via a mild [4+2] Diels-Alder cycloaddition reaction with fullerene C to enhance the performance of organic solar cells (OSCs). Comparative analysis shows that C-Y significantly outperforms the control acceptor Me-Y, with a notable increase in the relative dielectric constant from 2.79 to 3.

In this work, we study the near-edge x-ray absorption fine-structure (NEXAFS) spectra of 2,7-didecyl[1]benzothieno[3,2-b][1]benzothiophene (C10-BTBT) at both the carbon and sulfur K-edges. Angle-resolved experiments of thin films are performed to characterize the dichroism associated with molecular orientation.
