| Aromatic metal compounds might be usable as highly efficient
| catalysts for organic reactions. These compounds could be used to
| create novel materials with interesting electronic, optical, or
| magnetic properties, so we could see better organic LEDs, better
| organic solar cells, conductive polymers, and improvements to
| magnetic materials for data storage. The unique structures of
| aromatic metal compounds could be exploited in drug design,
| potentially leading to new classes of therapeutic agents with
| improved efficacy or novel mechanisms of action. These compounds
| might be also used to create new types of nanostructures or
| improve existing ones, with potential applications in areas like
| sensing, drug delivery, or nanoelectronics. The electronic
| properties of aromatic metal compounds could potentially be
| harnessed to develop new types of batteries or supercapacitors
| with improved performance. The specific interactions between
| aromatic metal compounds and various analytes could be used to
| develop highly sensitive and selective chemical sensors. These
| compounds might exhibit interesting photochemical properties,
| leading to advancements in areas such as photocatalysis or light-
| harvesting materials for solar energy conversion.

| We will know in ten years!

| rock and made those same claims.

| Enhanced electron delocalization and mobility. Metals often

| p-orbitals of the aromatic system. Aromatic systems already
| possess delocalized electrons in their p-orbitals. This
| delocalization allows for easier electron movement within the
| molecule. This helps with electron transfer in reactions when
| using catalysts and it is also useful for applications which
| benefit from improved conductivity.

| Relevant passage from the Nature article
| (https://www.nature.com/articles/s41557-024-01530-z)
| During our investigation of 2 as a transmetallation agent, we
| observed an unusual reactivity with InBr3. The reaction of 2 with
| InBr3 in dichloromethane resulted in a rapid colour change from
| light orange to dark red. After standing for 3 days at room
| temperature, dark-coloured crystals of 3 developed (Fig. 3f). The
| synthesis is reproducible, yielding up to 28% of isolated 3.
| scXRD analysis showed a planar rhomboid {Bi4} ring encapsulated
| by two indiumbromide-calix[4]pyrrolates (...)
