Herein we present our successful synthesis of 19c-boratribenzogh,jk,mn6helicene, the hitherto longest and first configurationally stable pristine boranhelicene. It displays intense orange fluorescence and circularly polarized light (CPL) emission with a high quantum yield of up to 84%. X-ray single crystal analysis reveals a highly twisted, helical shape and intriguing intermolecular stacking. Complexation with a size-complemental aza4helicene yielded an unprecedented hetero-chiral π–π-stacked helicene dimer.
