Trianguleniums are fascinating conjugated hexacyclic cations that exhibit interesting electronic and optical properties. Herein, the electrogenerated chemiluminescence (ECL) emission of this family of fluorescent dyes is reported for the first time. Redox behavior and fluorescence properties of eight cationic triangulene luminophores with different heteroatom patterns in the core structure and various pending substituents were examined to rationalize the ECL. Clearly, the more electron-rich the carbocations, the more efficient the corresponding ECL and two very distinct classes of triangulenes can be drawn from these studies using an ECL wall sufficiency formalism.


The authors of this work were alerted to an error in the reported electrochemical potentials values.

This series of corrections does not affect at all the validity of the interpretations and of the conclusions of the original Full Paper. However, these corrections are necessary to enable a valid comparison of the electrochemical potentials values with other structurally related compounds reported in the literature.

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.
