Novel Phosphazenium Tetrafluoroborate Dopant Enables Efficient and Thermally Stable n‐Doped Organic Semiconductors

Advanced Electronic Materials, EarlyView.
A novel n‐dopant, phosphazenium tetrafluoroborate (P2BF4), is introduced for efficient n‐doping in N2200, P(PzDPP‐CT2) and other organic semiconductors (OSCs). P2BF4‐doped OSC films exhibit exceptional thermal stability, maintaining electrical conductivity after heating at > 150 °C for 24 h. This stability allows organic thermoelectric devices based on

One‐Dimensional Polycyclic Aromatic Hydrocarbons Incorporating Multiple Dithiafulvene Units—Novel Multi‐Redox and Electrochromic Systems

Angewandte Chemie, EarlyView.
Planar polycyclic aromatic hydrocarbons (PAHs) incorporating three or four dithiafulvene (DTF) units were synthesized via Horner–Wadsworth–Emmons reactions to create large π‐conjugated redox‐active frameworks. These molecules display strong intermolecular associations and distinct odd–even redox behavior, enabling formation of mixed‐valence and radical‐

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

Advanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...

Self‐assembled Helical Tetramer Stack of Terrylene Bisimide in Solution and Crystalline State

Angewandte Chemie, EarlyView.
A TBI with sterically demanding imide substituents self‐assembles in solution into a defined helical tetramer π‐stack. Both the monomer and the tetramer can form complexes with polycyclic aromatic guest molecules, resulting in the formation of tri‐ or hexalayer in solution and in the crystalline solid state.

Peripherally Fluorinated Tetraphenylethene: New Electron Extraction Interlayers for n‐i‐p Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Fluorinated tetraphenylethene (TPE) derivatives were developed as interfacial layers for perovskite solar cells. The optimized TFP‐TPE enhances interfacial compatibility, suppresses molecular aggregation, and improves charge extraction. Devices incorporating TFP‐TPE achieved a record efficiency of 25.29% and outstanding stability under humidity and ...

Selective Ion‐Blocking Strategy for Stabilizing Perovskite Tandem Solar Cells

Advanced Energy Materials, EarlyView.
A selective ion‐blocking Li─T interlayer is introduced at LiF‐passivated perovskite interfaces to suppress fluorine diffusion while preserving the beneficial interfacial passivation of LiF. This ion‐blocking strategy markedly improves the long‐term operational stability of both single‐junction and monolithic all‐perovskite tandem cells under continuous
