Finally, it was earlier argued that the dication of 1 in its triplet state ( 3 1 2+ ) is Bairdaromatic in one of the cycles since it has a NICS(0) value of -2.6 ppm, a value that suggests a modest Baird-aromaticity (if any). Following the argumentation in the section on qualitative theory, we tested if Baird-aromaticity is also achieved in the quartet state of the trication, and find that 4 1 3+ is D3 symmetric at its global minimum having an electron delocalization of 59% (EDDB), and a similar delocalization is found in the triplet dication ( and which are true 3D-aromatics? Four conditions should be satisfied according to the definition given in the Introduction. Both the 6n + 2 electron count and the orbital topology requirements must be fulfilled in such molecules, and the molecular properties should be similar in all three directions. Furthermore, they should exhibit extensive electron delocalization in radially oriented -orbitals, and it should be larger than the delocalization for analogous species with other electron counts than 6n + 2. In the theory section, we outlined the design of tetrahedral and cubic -conjugated molecules which may be true 3D-aromatics (see Figure ).
