We are happy to share our last J. Am. Chem. Soc. paper on the synthesis by Prof. Zhong-Ming Sun's group (Nankai Univ.) of an endohedral inorganic fullerene with spherical aromaticity. Aromaticity analysis by amclabs @aromaticity_eu Miquel Solà. #ChemTwitter pubs.acs.org/doi/10.1021/ja…

σ-bonding pattern in Bi4(4+) is truly intriguing! Three MOs (B2u,Ag,B1g) interfer in a way that disrupt coherence in the entire Bi4 ring but not in the Bi3 subunits. So, is it really the four-membered σ-aromatic ring or two three-membered σ-aromatic "rings" fused together?

Excellent paper, congratulations! Those systems are very hard to model at DFT as the topology of d-orbital conjugation differs depending on XC used. Anyway, EDDB confirms delocalization and potential aromaticity.

nature.com/articles/s4155… - The C5 ring inside seems to have rather well localized pi-bonds and the positive charge stabilized via resonance by one of the C6F5 rings. Not a bad way to avoid antiaromaticity, isn't it? ;-)

But what if I told you that the Aza-SuperNaphthalene cations are not globally (anti)aromatic? It should be realized that in topologies other than simple monocycles it is generally not possible to decipher the resonance bonding patterns (i.e., the distribution of pi-electrons

Today, Miquel Solà presented in the MAGIC 2024 congress the work our group (Sílvia Escayola Albert Poater) has done on double aromaticity in collaboration with Jordi Poater Henrik Ottosson (prefer Bluesky) Nathalie Proos Vedin and F. Teixidor and C. Viñas at icmabCSIC

Global π-aromaticity in conjugated macrocycles does not stem from the resonance of Kekulé structures but from the superposition of Clar structures that already possess local π-aromaticity: "Decoding Aromaticity in the [24]paracyclophanetetraene Anions" go.shr.lc/3Y7ZjJb

Exciting theoretical study, especially “de-convolution” of the AICD plots of these anions summarizing what @aromaticity_eu has been tweeting a lot about. Imho if real and correct, this is quite revolutionary for the field. Now grabbing popcorn 🍿and waiting for comments.(1/2)

Unpopular opinion: I don't like ML, AI, NN, or anything resembling it. I like to understand why, and to (theoretically) engineer molecules with my own hands. I'm glad others work with ML, and not me. Let's see chemistry tomorrow! PS: I have this picture hanged in my lab:
