Incorporation of an Extended Electron‐Deficient Central Block Into Small‐Molecule Acceptors Toward Enhanced‐Performance Organic Solar Cells

Aggregate, Volume 7, Issue 6, June 2026.
Two novel extended electron‐deficient central cores (Tz‐Qx, Dz‐Qx) with F/Cl‐substituted terminal groups synergistically optimize small molecule acceptors. Tz‐Qx‐4F outperforms Dz‐Qx‐based counterparts, achieving 19.50% PCE (29.3 mA cm−2 JSC) when blended with D18, thus providing valuable insights for designing high‐performance organic solar cell ...

Acceptor Derivatization of the 4CzIPN TADF System: Color Tuning and Introduction of Functional Groups

ChemistryOpen, 2019
We demonstrate modular modifications of the widely employed emitter 2,4,5,6‐tetra(9H‐carbazol‐9‐yl)isophthalonitrile (4CzIPN) by replacing one or both nitrile acceptors with oxadiazole groups via a tetrazole intermediate.
