Interplay of Bridge Topology and Conformation in Phenylene‐Bridged Trityl Diradicals

Chemistry – A European Journal, EarlyView.
We present a meta‐phenylene‐bridged trityl diradical that exhibits an unexpectedly weak antiferromagnetic exchange coupling J with a strong environment‐dependent magnitude. Combined VSM, EPR, DFT, and MD studies reveal that structural flexibility modulates σ‐, π‐, and through‐space exchange contributions, highlighting the crucial role of geometry in ...

Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

Chemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

Cyclization of a 1,8‐Diphenylanthracene by Scholl Reactions to Form Five‐ and Seven‐Membered Ring Embedded Polycyclic Aromatic Hydrocarbons

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.

Morphological Transitions in the Self‐Assembly of Rigid Sphere–Rod Amphiphiles Achieved by Adjusting the Linker Length

Chemistry – A European Journal, EarlyView.
Linker length regulates the self‐assembly of rigid sphere–rod amphiphiles. Long linkers enable rigid sphere–rod molecules to undergo solvent‐dependent conformational switching between I‐ and T‐shaped states, driving morphological transitions of the assemblies from striped spherical structures to onion‐like structures.
