Starting from the highly symmetric and very weakly fluorescent 2T-N, 2T-7N (see Fig. ) and 2T-4N (see Fig. ), we moved to fluorescent 2T-3N and 2T-4N' (see Fig. ), obtained by decorating the edge of 2T-N with two and three N atoms, respectively. In all cases, we found non-negligible regions of the parameter space showing ST inversion. We demonstrated that neither the presence of C 2 axis and σ v plane, nor the very specific connectivity of triangulenes are actually needed for ST inversion.
