Descriptor‐Guided Computational Screening of Non‐Fullerene Acceptor Cores for Organic Solar Cells

Advanced Energy Materials, EarlyView.
We screen over 4000 non‐fullerene acceptors using their ionization energy, electron affinity, quadrupole, and dipole moments to select the top‐ten candidates for a given donor polymer. The workflow recovers known high‐performance motifs and reveals how molecular components influence material properties.

Extending El Sayed's Rule by 1(n,π*)–3(n,π*) Rotation via Intramolecular Secondary Interaction Enables Room‐Temperature Circularly Polarized Phosphorescence in Solution

Angewandte Chemie, EarlyView.
Weak but skilled: Our results highlight the crucial role of intramolecular secondary interactions to induce an efficient ISC between formally identical 1(n,π*) and 3(n,π*) states in chiral thionated phthalimide derivatives. This unprecedented type of inter‐system crossing (ISC) extends the usual thinking of the El‐Sayed principle and enables the ...

An X‑Shaped Chiral Non‑Fullerene n‐Type Semiconductor: Application in Perovskite Solar Cells and Chirality‑Induced Spin Selectivity

Angewandte Chemie, EarlyView.
A highly electron‑accepting derivative of cyclobisbiphenylenecarbonyl (CBBC‐TIC) is reported. CBBC‐TIC functions as an electron‐transport layer for perovskite solar cells, achieving a power conversion efficiency of 20.6%. Furthermore, the enantiomers of CBBC‐TIC exhibited spin‐selective electron transport with high enantiospecific magnetic conductance ...

TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

Angewandte Chemie, EarlyView.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...

Fluorene‐Framework Engineering Enables Narrowband Red Multi‐Resonance Emitters for High‐Efficiency With Negligible Roll‐Off Toward BT.2020

Angewandte Chemie, EarlyView.
σ‐Decoupled C9 fluorene‐framework topology control enables narrowband red MR emitters. SF‐BNO and PF‐BNO share the same BNO core, but differ in closed/open fluorene ring closure. SF‐BNO improves steric shielding and stability, while PF‐BNO enhances PLQY, orientation, and efficiency. Ex‐PSF and TE‐OLED architectures deliver ultra‐low efficiency roll‐off
