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

open access: yesFlexMat, 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.

Non‐fullerene acceptor aggregation regulation via additives dipole moment leads to 19.9% power conversion efficiency in bilayer organic solar cells

open access: yesFlexMat, EarlyView.
Additives interact with non‐fullerene acceptors to modulate their aggregation behavior and molecular orientation via optimizing crystallization kinetics. The optimized morphology effectively suppresses charge carrier recombination and enhances charge transport. Notably, 2‐chloro‐1,3‐dibromobenzene with the dipole moments of 2.56 D enables the PM6/L8‐BO

How (not) to Cage an Electron: The Perfluoro Cage Effect as an Extrinsic Molecular Property

open access: yesHelvetica Chimica Acta, EarlyView.
A rigorous definition within Kohn–Sham density functional theory is presented for the notion of an caged electron inside perfluorinated fullerenes as radical anions. ABSTRACT The notion of a (molecular) electron cage was coined for the unique hosting capacity of perfluorocubane, suggesting the “encapsulation of an electron” within the highly symmetric ...

Quantitative Correlation Between Charge Transfer and Two Photon Absorption in Phenanthridine‐TCNB Cocrystal

open access: yesInformation &Functional Materials, EarlyView.
A new molecular cocrystal shows D‐A alternative molecular stacking, cyan‐blue photoluminescence with lifetime of 19.76 ns, and two‐photon absorption enabled emission under laser excitation between 720 and 880 nm. Theoretical calculations reveal its static dipole moment of 2.84 D, CT character in the ground, S1, and S2 excited states, and the TPA ...
