A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, EarlyView.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

Controlling the Guanidinium Cation Rotation by Cation–π Interactions

Angewandte Chemie International Edition, EarlyView.
A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.
