4N electron aromatic cycles in polycyclic hydrocarbons
文献情報
Michael Mauksch, Svetlana B. Tsogoeva
Polycyclic fully conjugated hydrocarbons in which aromatics are fused to aromatics – or aromatics to antiaromatics – are important as potential organic semiconductors. Herein we explore the only remaining fusion pattern of antiaromatics to antiaromatics. It is shown computationally that the central antiaromatic unit (cyclobutadiene or pentalene) in such a three-unit polycyclic hydrocarbon, generated by fusion of three antiaromatic molecules, turns aromatic according to magnetic shielding (NICS) criteria. The resulting neutral 4N electron molecules possess a 4N π electron perimeter with pronounced CC bond length equalization (as indicated by the HOMA geometric index) and significant aromatic stabilization energies (computed using the isomerization-stabilization method) and could be promising synthetic targets with small HOMO–LUMO gaps.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
