Nucleophilic Reactions of Cyclobutenones and the Related 4,4‐Dichlorocyclobutenone Derivatives

European Journal of Organic Chemistry, EarlyView.
Cyclobutenone derivates and their 4,4‐dichloro counterparts have an uninterrupted attention as useful synthons in the synthesis of complex organic molecules. Their nucleophilic reactions remain underexplored. This review brings attention to these reactions, whose outcome is not straightforward.

4,4′-(Acridine-2,7-diyl)bis(2-methylbut-3-yn-2-ol)

IUCrData
The title acridine derivative, C23H21NO2, which has two 2-methylbut-3-yn-2-ol moieties at the 2,7-positions, was synthesized by Sonogashira coupling reaction. In the crystal, a columnar structure is formed by the π–π stacking of acridine units.

Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

FlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.
