FlexMat, EarlyView.A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Tuning Covalent Organic Frameworks via Nucleophilic Aromatic Substitution. [PDF]
Small SciThe direct nucleophilic aromatic substitution reaction on a fluorinated covalent organic framework leads to functional materials bearing bulky pendant groups such as carbazole or ferrocene. The method is versatile, suitable for O‐, S‐, and N‐based nucleophiles, and provides a unique conjugated structure containing electron‐withdrawing fluorine atoms ...

FlexMat, EarlyView.An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...

Flexible organic room‐temperature phosphorescent materials
FlexMat, EarlyView.This review highlights recent advances in flexible organic room‐temperature phosphorescent (RTP) materials, covering both organic crystal and polymer systems. It discusses strategies to overcome the inherent rigidity and enhance the mechanical flexibility of organic RTP materials, aiming to enable their practical applications in anti‐counterfeiting ...

Indole‐Based π‐Extended Monophosphine Ligands for Enhanced Palladium‐Catalyzed Sonogashira Coupling
Journal of Heterocyclic Chemistry, EarlyView.A general palladium‐catalyzed Sonogashira cross‐coupling of (hetero)aryl chlorides with aliphatic, (hetero)aryl alkynes is described using Pd(dba)₂/PCy2‐Napdole‐phos catalyst system. The reaction protocol exhibits broad substrate scope and the catalyst loading can be down to 0.2 mol% Pd.
