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.

Polymeric fullerenes : from C60 to C70

, 1999
For the first time polymerization of both powder and single crystals of C70 fullerene was established after their subjection to high pressure (1.1-2.0 GPa) at elevated temperature (500-580 K).

DFT study of interaction of acetylene and C70 fullerene molecules

Chemical Physics Impact
The interaction between the C70 fullerene and acetylene was investigated using DFT calculations (DFT/B3LYP/6–31G (d, p)). It is shown that the C72H2 formation proceeds through sequential [2 + 1], [2 + 2], and [3 + 2] cycloaddition reactions.

Enhanced Electron‐Capturing by Single‐Atomic Iron on Pyridinic N‐Deficient Carbon Drives Self‐Oxidative Degradation of Pollutants

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Pyrolysis of FeOx/g‐C3N4 and ZIF‐8 is performed to introduce Fe single atom and pyridinic nitrogen vacancies onto N‐doped carbon. This modification enables the materials to efficiently extract electrons from ciprofloxacin (CIP) and activate dissolved oxygen. 100% of CIP was degraded within 1 min without adding any oxidant.
