nanographene - thermal isomerization - polycyclic aromatic hydrocarbons - stereoisomers

Significance

An unprecedented, large molecular carbon, having a polycyclic aromatic surface composed of 85 fused hexagon rings, is synthesized. The nonplanar skeleton hampers compact π–π stacking and bestows good solubility, thus allowing comprehensive structural characterizations.


 

Comment

The nonplanar polycyclic framework is found to undergo thermal isomerization, which renders a highly symmetrical isomer to be isolated. Single-crystal XRD analysis unambiguously proves the molecular structure.
