Abstract
Chirality is an important and fascinating concept which has not been properly addressed in nanocarbons science.1 We have previously reported the first inherently chiral bilayer nanographene with a helicene linker, both as the racemate and the M isomer.2 By extending precedented [6]helicene starting material, we obtained an unprecedented chiral nanographene comprised of two hexa-peri-hexabenzocoronene layers fused to a [10]helicene. Furthermore, we have also described a bottom-up synthesis of structurally well-defined curved nanographenes from corannulene, affording inherent helicenes in the resulting molecular nanographene.3 These nanographenes are appealing systems for the study of further chemical reactions including supramolecular interactions.4,5 In this presentation, the recent findings on nanographenes and on-surface π-conjugated polymers6 will be discussed.
