• investigating the ion-pairing assemblies. Results and Discussion The N-(2,6-dimethylphenyl)-substituted triazatriangulenium cation 2+ was synthesized as a BF4− ion pair 2+-BF4− in 19% yield using a modified synthetic procedure for 2+-Cl− [30] (Figure 2). It should be noticed that the SNAr reaction for ring
