Bulletin of the Korean Chemical Society, EarlyView.Excited‐state absorption (ESA) spectra are notoriously hard to compute. We show that routine DFT and TDDFT vibronic transition calculations reproduce the vibronic band shapes and positions of azulene's experimental ESA spectrum, providing a practical route to assign ESA bands to specific electronic transitions and vibrational modes.

A Multi‐Stimuli Transformational Network of Benzil‐Based Pd(II) Assemblies
Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.Incorporation of a flexible and chemically reactive benzil backbone into the ligand structure allows it to access multiple conformations, enabling the formation of diverse homo‐ and heteroleptic Pd(II) assemblies with different nuclearities and topologies.

Beilstein Journal of Organic Chemistry, 2018 Some of the least studied calixarenes are those that consist of azulene rings bridged by -CH2- groups. Since Lash and Colby’s discovery of a simple and convenient method for producing the parent all-hydrocarbon calix[4]azulene, there have been two other ...

Chemistry – A European Journal, EarlyView.Reactions of 10‐mesityl‐1,8‐diphenylanthracene with DDQ/TfOH produced three products via sequential formation of a five‐ or seven‐membered ring. Unexpectedly, the triply cyclized product with a rubicene substructure was formed through cyclization involving 1,2‐methyl shift.

Crystal structure of diethyl 2-amino-6-[(thiophen-3-yl)ethynyl]azulene-1,3-dicarboxylate
Acta Crystallographica Section E: Crystallographic Communications, 2015 The title compound, C22H19NO4S, has an almost planar geometry supported by intramolecular N—H...O and C—H...O hydrogen bonds. The thiophene ring is inclined to the azulene ring by 4.85 (16)°, while the ethoxycarbonyl groups are inclined to the azulene ...

Chemistry – A European Journal, EarlyView.Lighting up αVβ6: Halotryptophan engineering converts an RGD scaffold into a modular αVβ6 ligand platform, enabling picomolar affinity and late‐stage functionalization. The resulting probes combine high selectivity with fluorescence for FACS and tumor imaging.

A Colorimetric Chemosensor Based on a Nozoe Azulene That Detects Fluoride in Aqueous/Alcoholic Media
Frontiers in Chemistry, 2020 Colorimetry is an advantageous method for detecting fluoride in drinking water in a resource-limited context, e. g., in parts of the developing world where excess fluoride intake leads to harmful health effects.
