Mapping the Chemical Space of TADF Sensitizers Coupled with Virtual Screening for Narrowband Hyperfluorescence OLEDs

Yayin Deng, Yimin Wu, Xingliang Wang, Xiaoyu Liu et autres

Abstract Developing efficient thermally activated delayed fluorescence (TADF) sensitizers for narrowband red hyperfluorescence organic light-emitting diodes (HF-OLEDs) remains a major challenge because long-wavelength sensitization requires the simultaneous optimization of a small singlet–triplet energy gap (ΔEST), a low singlet excited-state energy (ES1), and …

Energy Transfer Catalysis Enabled by Multichannel Through‐Space Charge Transfer TADF Photosensitizers: [2 + 2] Photocycloaddition to Cyclobutane‐Fused Phosphindole 3‐Oxides

Jingjing Zhang, Dongle Li, Yuyang Tang, Ruobing Li et autres

ABSTRACT Triplet energy transfer (TEnT) photocatalysis has emerged as a powerful tool for enabling mild and selective bond‐forming reactions. However, its generality remains limited by the intrinsic trade‐offs in existing photosensitizers (PSs). Noble metal (e.g., Ir, Ru) complexes offer high efficiency yet …

NOTCH3 R545C mutation drives vascular-neuronal dysfunction and cognitive impairment in CADASIL pathogenesis

Suning Ping, Bin Hu, Danni Wu, Can Wan et autres

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common hereditary small vessel disease caused by mutations in the NOTCH3 gene. However, its pathogenic mechanisms remain incompletely understood. Given the high prevalence of the NOTCH3 p.Arg544Cys (R544C) mutation …

Multi-terphenyl steric shielding enables simultaneous efficiency enhancement and emission narrowing in multi-resonance emitters

Mufan Yang, Yuxuan He, Jingbo Lan, Jingsong You et autres

We herein report a stepwise terphenyl steric shielding strategy to construct novel B,N-embedded multi-resonance emitters, which greatly suppresses electroluminescence redshift and spectral broadening. Target molecule 2TP-BN achieves 25.6% maximum external quantum efficiency and narrow full-width at half-maximum of 26 nm, supplying a …

Precise Synthesis of Pyrene-Based Molecular Nanocarbons Driven by Dehydro-Diels–Alder Reactions

Jian H. Li, Haohua Chen, Ya Wang, Yimin Wu et autres

Molecular nanocarbons are critical bridges between small polycyclic aromatic hydrocarbons and extended graphene lattices, driving advances across materials science, optoelectronics, and quantum technologies. However, the atomically precise synthesis of such systems, particularly those featuring K-region and cove-type topologies, remains an enduring challenge. …

Chengming Li, Weihua Zhuang, Yongjie Zhou, Linfeng He et autres

Synthetic control over multiple conformations of expanded porphyrinoids, which are intrinsically linked to their properties and functions, has long been a key objective in chemical research. Here, we present an N-substituent-controlled synthesis of 3,6-carbazole-based octaphyrins and dodecaphyrins via modified Rothemund-type condensation. The …
