Harnessing the Orientation of Columnar Discotic Liquid Crystals for Narrowband Blue Emission with Enhanced Out‐Coupling Efficiency Toward Improvement of SP‐OLEDs Performance

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Solution‐processed OLEDs containing discotic liquid‐crystalline MR‐TADF emitters are reported. Supramolecular self‐assembly induces homeotropic columnar alignment, enforcing preferential horizontal orientation of the emitter transition dipole moment in spin‐coated films, which leads to an enhancement in the device light outcoupling efficiency while ...

Ubiquitous Antiparallel Domains in 2D Hexagonal Boron Nitride Uncovered by Interferometric Nonlinear Optical Imaging

Advanced Materials, Volume 38, Issue 25, 4 May 2026.
Interferometric second‐harmonic generation (SHG) imaging reveals the ubiquitous formation of antiparallel domains in CVD‐grown 2D hexagonal boron nitride. By resolving lattice orientation and SHG phase, hidden domain structures and disorder become visible over large areas. The SHG intensity quantitatively tracks crystalline quality across growth routes,

Octupolar AIEgens Photosensitizers With Enhanced Molar Absorptivity for Near‐Infrared Phototheranostics

Aggregate, Volume 7, Issue 5, May 2026.
Symmetry‐guided molecular engineering transforms dipolar AIEgens into octupolar AIEgens (D(A)3) with enhanced NIR‐II absorptivity. The octupolar architecture activates additional S0→S2 transitions and promotes efficient intersystem crossing, leading to strong reactive oxygen species generation.

Dual‐Phosphorus, Dual‐Nitrogen‐Embedded Corannulene: Synthesis, Structure, and Electronic Coupling

ChemistryEurope, Volume 4, Issue 5, May 2026.
P2N2‐TBC, a corannulene‐based bowl structure incorporating two phosphorus and two nitrogen atoms, represents the first P2N2‐embedded heterobuckybowl. The cis and trans stereoisomers of this compound display distinct packing motifs, leading to markedly different electronic coupling patterns.

Chiral Heptagon‐Embedded Double [6]Helicenes via Scholl Reaction

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
One bond makes the difference–two chiral and twisted polycyclic aromatic hydrocarbons (PAHs) show different emission behavior. The more flexible one (top) shows a double emission with one having a large anti‐Stokes shift. The two peaks are assigned to different conformers of one and the same compound.

Organic neuromorphic electronics powering intelligent sensory and edge computing systems

InfoMat, Volume 8, Issue 5, May 2026.
Organic electronic materials are promising candidates for neuromorphic sensing applications, including chemical, physical, visual, and multimodal sensing, owing to their mechanical softness, biocompatibility, and intrinsic ionic–electronic coupling.
