Resumen
Different theoretical methodologies were applied to a series of substituted benzenes C6X6 (with X = H, F, Cl, Br and I) to pursue the property of aromaticity. HOMA (as structural criterion), NICS (FIPC-NICS, isotropic and ZZ employed as magnetic criteria) as well as the indexes ASE, MCI, PDI and FLU, interestingly provided controversial data respect to the magnetically induced current density plots and chemical intuition, which is extensively discussed in the herein work. Furthermore, EDA-NOCV was used to complement the rational explanation of the observed results. © 2019 Elsevier B.V.

Guajardo‐Maturana, Raul; Rodríguez-Kessler, Peter L.; MacLeod‐Carey, Desmond; Muñoz‐Castro, Álvaro (John Wiley and Sons Inc., 2020-09-05)The NMR characterization of small C36 hollow fullerene exposes a stable cage with structural features based on its strained curved π-surface in a D6h-symmetry. Our results indicate that planar-like aromatic properties of ... -

Switch from local to global aromatic character in Möbius carbon nanobelts upon dioxidation. Evaluation of magnetic behavior in neutral and charged species (2023)
Macleod-Carey, Desmond; Muñoz-Castro, Alvaro (Royal Society of Chemistry, 2023)Here we show that recent Möbius carbon nanobelts (MCNBs) can be switched from a local to a global aromatic behavior upon dioxidation. Hence, large aromatic structures can be achieved by the choice of the charge states, ...
