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

open access: yesChemistry – 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.

Central sp3‐C Substitution Directs Supramolecular Assembly and Molecular Properties of Tris‐HBC Nanographenes

open access: yesChemistry – A European Journal, EarlyView.
Central sp3‐C substitution (─H, ─OH, ─CH3, ─OCH3, and ─OC2H5) directs supramolecular packing in tris‐HBC (hexa‐peri‐hexabenzocoronene) nanographenes, yielding diverse layered and porous architectures via modulation of intermolecular interactions. Comprehensive Raman, NMR, photophysical, and electrochemical analyses, supported by DFT/TD‐DFT calculations,
