Invited Lecture – Nazario Martín

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.
