3D and 2D aromatic units behave like oil and water in the case of benzocarborane derivatives

Nature Communications, 2022
2D/2D fusion of aromatic halves leading to a global aromatic is found in many polycyclic aromatic hydrocarbons, whereas 2D/3D aromaticity is difficult to achieve. Here the authors report a computational chemistry investigation showing that 3D/2D aromatic
