Synthesis of Long-Sought C-66 with Exohedral Stabilization
- 化学化工－已发表论文 
Previously reported fused-pentagon fullerenes stabilized by exohedral derivatization do not share the same cage with those stabilized by endohedral encapsulation. Herein we report the crystallographic identification of (C66Cl10)-C-#4348, which has the same cage as that of previously reported Sc-2@C-66. According to the geometrical data of (C66Cl10)-C-#4348, both strain relief (at the fused pentagons) and local aromaticity (on the remaining sp(2)-hybrided carbon framework) contribute to the exohedral stabilization of this long-sought 66 carbon atom cage.
