The Smallest "Carbon Nanoring" [5]Cycloparaphenylene ([5]CPP)

Structural Feature
・ CPP having the smallest ring size among synthesized other examples
・ Cyclic unit structure of fullerene (C60) and [5,5] carbon nanotube
・ The same diameter as C60 (0.7 nm)

Properties
・ Soluble in organic solvents
・ Narrow HOMO-LUMO gap comparable with that of C60

Description


Possible application
・ Organic electronics materials
・ Raw material for carbon nanoring derivatives, and bottom up synthesis of CNT
・ Molecular host materials
