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.2,3 By extending precedented [6]helicene starting material, we obtained an unprecedented chiral nanographene comprised of two hexa-peri-hexabenzocoronene (HBC) layers fused to a [10]helicene . Furthermore, we have increased the family of bilayers by using the respective [5] and [7]helicenes, affording bilayers with [9] and [11]helicenes, respectively. These nanographenes are appealing systems for the study of further chemical reactions including redox reactions.4 In this presentation, the recent findings on this singular family of chiral nanographenes showing remarkable CPL values, as well as their less known outstanding photophysical properties will be discussed.
