Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

Chemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Vibrational Circular Dichroism Spectra of 2,5‐Diaminoterephtalate Macrocycles Reveal Distant Vibrational Exciton Coupling

Chemistry – A European Journal, EarlyView.
The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

Light, Redox, and Ligand Noninnocence Cooperate in Naphthalene Diimide‐Functionalized N‐Heterocyclic Carbene Iridium Complexes

Chemistry – A European Journal, EarlyView.
Naphthalene diimide–N‐heterocyclic carbene iridium complexes display uncommon multistimuli‐responsive behavior combining strong Cl(lp)···π interactions, ligand non‐innocence, visible‐light photoreduction, and conPET photocatalysis. The study also provides new insight into the interaction of NDI platforms with fluoride/basic anions, revealing unexpected
