Physicochemical properties of cationic dioxa, azaoxa and diaza [6]helicenes demonstrate (i) a remarkably high chemical stability of these cationic adducts, (ii) fluorescence from the orange to the far-red regions with non-negligible quantum yields and lifetimes, (iii) circularly polarized luminescence in the same ranges. Selective post-functionalization of the diaza [6]helicene introduces peripheral auxochrome substituents (12 examples). Their influence on the optical properties is rationalized by first-principles calculations.

Corrigendum:

The authors have been alerted to an error in the reported electrochemical potential values.

This correction does not affect the validity of the interpretations and of the conclusions of the original Full Paper.

The authors sincerely apologize for this error and would like to thank Professor Bo W. Laursen from the University of Copenhagen, Denmark for drawing their attention to this matter.
