Fluorescent Zinc(II) Complexes with a N,N,N‐Tridentate Ligand Based on the Bis(imidazo[1,5‐a]pyridine)methane Scaffold

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The coordination behavior of bis(imidazo[1,5‐a]pyridine)methane derivatives has been expanded through functionalization with a methylpyridine pendant arm, affording new tripodal N,N,N‐tridentate ligands. Upon coordination to zinc(II), the resulting (chiral) complexes retain the attractive luminescent properties of the ligand platform, displaying ...

π‐Extended Silyl Enolates as Emerging Platforms in Radical Chemistry

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review covers the emerging role of π‐extended silyl polyenol ethers in radical chemistry. It highlights their versatile roles as electron‐rich SOMOphiles, silyl radical cation precursors, and nucleophilic partners in radical–polar crossover manifolds, while considering recent advances in photoredox catalysis, electrochemistry, and transition metal‐

Diarylethene‐Containing Photoswitchable Analogues of Tubulysins—Design, Synthesis, Biological, and Structural Evaluation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Diarylethene‐containing cyclic tubulysin analogues were designed, synthesized, and evaluated as light‐responsive cytotoxic agents. One analogue showed reversible photoswitching, photoregulated tubulin polymerization inhibition, and photoform‐dependent cytotoxicity.

Regioselective Oxidative Oligomerization of 2‐Tert‐Butylpyrene Toward Structurally Defined Oligomers and Their Application in Organic Light‐Emitting Diodes

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Treatment of 2‐tert‐butylpyrene with Cu2+ afforded structurally well‐defined pyrene oligomers, up to the 13‐mer. Single‐crystal X‐ray diffraction, spectroscopic analyses, and computational studies were conducted to evaluate the properties of the resulting oligopyrenes.

Modular π‐Extended IF‐TTF Systems: Tuning Redox and Optical Properties in Donor–Acceptor and Donor–Donor Frameworks

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Donor–acceptor and donor–donor systems incorporating an indeno[1,2‐b]fluorene‐extended tetrathiafulvalene (IF‐TTF) donor motif were prepared by Suzuki coupling reactions. The compounds were studied for their optical and redox properties. The compounds showed multiredox behavior with several accessible redox states. A series of π‐extended donor–acceptor

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

open access: yesFlexMat, 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 ...

Deep learning cone‐beam computed tomography image segmentation for the 3D visualization of mandibular infraosseous periodontal defects

open access: yesJournal of Periodontology, EarlyView.
Abstract Background The accurate assessment of infraosseous periodontal defects is crucial for effective diagnosis and treatment planning. Cone‐beam computed tomography (CBCT) enables detailed imaging of these defects; however, to leverage their full potential, CBCT images must be reconstructed in 3 dimensions (3D).
