Electronic Transport in Antiaromatic Molecules
Physical Chemistry Chemical PhysicsIt has been pointed out that antiaromaticity may, under certain conditions, enhance electron transport. Here, we explore this relationship by analyzing a representative series of antiaromatic molecules, ranging from small and large-sized monocyclic systems to polycyclic molecules.

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.

Diboron‐Embedded Heteroacenes With Systematically Varied Central π‐Skeletons and Fusion Modes
Helvetica Chimica Acta, EarlyView.We synthesized diboron‐embedded acenes and revealed that fusion mode governs electronic properties, whereas molecular symmetry dictates crystal packing. One C2v‐symmetric isomer forms a uniform columnar π‐stacked array. ABSTRACT Diboron‐embedded heteroacenes with systematically varied central π‐skeletons and fusion modes were synthesized via one‐pot ...

Reversal of Clar's Aromatic‐Sextet Rule in Ultrashort Single‐End‐Capped [5,5] Carbon Nanotubes
ChemistryOpen, 2020 The three‐fold HOMO‐LUMO gap oscillation, typical of finite length armchair carbon nanotubes (CNT), has a major effect on the magnetic response of ultrashort, single‐end‐capped [5,5] carbon nanotubes to a perturbing magnetic field parallel to the main ...
