Selenophene‐substituted A‐D‐A‐type non‐fullerene acceptors for organic solar cells with an ultra‐high short‐circuit current density of 27.14 mA cm−2

FlexMat, EarlyView.
Two novel narrow bandgap electron‐deficient acceptors 6TFSe‐4F and 6TFSe‐4Cl were rationally constructed via synergistic core fluorination, selenophene substitution, and alkylation, enhancing donor‐acceptor molecular electrostatic potential difference to improve exciton dissociation and reduce energy loss.

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

FlexMat, EarlyView.
An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...
