Go to three dimensions : As a step toward a bottom‐up synthesis of size‐defined carbon nanotubes (CNTs), [3] cyclo ‐4′,4′′′′‐hexaphenylbenzenes ([3]CHPBs) were synthesized and investigated. Theoretical and experimental results revealed that [3]CHPBs possess highly twisted [9] cyclo ‐ p ‐phenylene cores. [3] cyclo ‐2,11‐(Hexa‐ peri ‐hexabenzocoronene) ([3]CHBC) was also examined for CNT synthesis (see figure).
