Chemical Science, 2023 Aromaticity is one of the most deeply rooted concepts in chemistry. But why, if two-thirds of existing compounds can be classified as aromatic, is there no consensus on what aromaticity is? σ−, π−, δ−, spherical, Möbius, or all-metal aromaticity… why are

From mass to structure: An aromaticity index for high-resolution mass data of natural organic matter [PDF]
, 2006 Recent progress in Fourier transform ion cyclotron resonance mass spectrometry (FTICRMS) provided extensive molecular mass data for complex natural organic matter (NOM). Structural information can be deduced solely from the molecular masses for ions with

Hyperconjugative aromaticity and protodeauration reactivity of polyaurated indoliums
Nature Communications, 2019 Hyperconjugative aromaticity combines the concepts of hyperconjugation and aromaticity and explains cyclopentadiene stability. Here, the authors demonstrate extended hyperconjugative aromaticity in a metallated indole ring, which shows extended electron ...

Excited-State (Anti)Aromaticity Explains Why Azulene Disobeys Kasha’s Rule
Journal of the American Chemical Society, 2023 Fluorescence exclusively occurs from the lowest excited state of a given multiplicity according to Kasha’s rule. However, this rule is not obeyed by a handful of anti-Kasha fluorophores whose underlying mechanism is still understood merely on a ...

Aromatic chloroosmacyclopentatrienes
National Science Review, 2022 ABSTRACT Aromatic metallacycles are of considerable current interest. Reported aromatic metallacycles are mainly those with carbon, nitrogen, oxygen and sulfur. In this work, we report the synthesis and characterization of aromatic chloroosmacyclopentatrienes, which represent the first structurally confirmed metallaaromatic with a ...

φ-Aromaticity in prismatic {Bi6}-based clusters
Nature Chemistry, 2022 The occurrence of aromaticity in organic molecules is widely accepted, but its occurrence in purely metallic systems is less widespread. Molecules comprising only metal atoms (M) are known to be able to exhibit aromatic behaviour, sustaining ring ...

Nanoscale Research Letters, 2009 Abstract Based on our comprehensive theoretical investigation and known experimental results for small boron clusters, we predict the existence of a novel aromatic inorganic molecule, B12H6. This molecule, which we refer to as borozene, has remarkably similar properties to the well-known benzene.

Too Persistent to Give Up: Aromaticity in Boron Clusters Survives Radical Structural Changes.
Journal of the American Chemical Society, 2020 o-C2B10H12 isomerizes to m-C2B10H12 upon heating at 400 ºC. Deboronation in o-C2B10H12 is a relatively easy process, whereas it is more difficult in m-C2B10H12. These two experimental facts indicate that m-C2B10H12 is thermodynamically more stable than o-
