The AICD analysis can directly append current density vectors on the isosurface corresponding to current intensity, thus graphically displaying various details of induced current of a molecular ring. As shown from AICD diagram in Figure , a distinct clockwise ring current is formed by π out -system under an external magnetic field, whereas the induced currents of π in -electrons are basically confined in straight carbon chain parts and fail to form a global delocalization. This indicates that C 18 Br 6 is only π out -aromatic and does not exhibit double aromaticity like C 18 , which is consistent with the chemical bond characteristics and electron delocalization picture obtained by IRI as well as LOL and ELF analyses. The AICD for all π-electrons, namely AICD-π all , shows a clear overall aromaticity of C 18 Br 6 . GIMIC is another effective method to reveal the magnetically induced current of a chemical system under the action of an external magnetic field, which can provide a complementary view on aromaticity with the AICD method. A distinctly clockwise current is observed along the carbon skeleton in Figure , so we can conclude the same as the AICD analysis that the C 18 Br 6 molecule is a global aromatic species. In the Supplementary Material, we provide an animation file of the ring current based on vector fields, which very intuitively shows the dynamic characteristics of the induced ring current.
