Tribenzotriquinacene Fused Dimers (“Fusodimers”)—Synthesis and Host–Guest Properties

Chemistry – A European Journal, EarlyView.
Two tribenzotriquinacene units merged with each other in either syn‐ or anti‐orientation of the bowls have become accessible in a short synthesis. In contrast to the anti‐isomer, the syn‐isomer forms 1:1 host–guest complexes with both C60 and C70 in solution and in the solid state, as shown by 1H NMR spectroscopy and x‐ray diffraction.

The Radical Chemistry of 2,3‐Diguanidinopyridines: Coordination and Visible‐Light Photochemistry

Chemistry – A European Journal, EarlyView.
Substitution at the pyridine core of 2,3‐diguanidinopyridines was used to develop novel redox‐active molecules with three interconvertible redox states. They are applied as redox‐active ligands in coordination chemistry. Visible‐light irradiation of the pyridine N‐benzylated molecules leads to photoconversion to a higher‐energetic isomer.

Vibrational Circular Dichroism Spectra of 2,5‐Diaminoterephtalate Macrocycles Reveal Distant Vibrational Exciton Coupling

Chemistry – A European Journal, EarlyView.
The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

Reversible Assembly and Disassembly of σ‐Aromatic B3 Rings

Chemistry – A European Journal, EarlyView.
B3 rings are the smallest σ‐aromatic boron compounds. Here, we show for the first time that cationic diboranes with an electron‐precise (2c,2e) bond can be reversibly converted to σ‐aromatic B3 rings with electron‐deficient (3c,2e) bonding. Base‐induced disassembly of the B3 ring leads back to cationic diboranes and monoborane adducts.

Light, Redox, and Ligand Noninnocence Cooperate in Naphthalene Diimide‐Functionalized N‐Heterocyclic Carbene Iridium Complexes

Chemistry – A European Journal, EarlyView.
Naphthalene diimide–N‐heterocyclic carbene iridium complexes display uncommon multistimuli‐responsive behavior combining strong Cl(lp)···π interactions, ligand non‐innocence, visible‐light photoreduction, and conPET photocatalysis. The study also provides new insight into the interaction of NDI platforms with fluoride/basic anions, revealing unexpected
