On Molecular Topological Characterization of Triangular and Rhombus
Shaped Kekulene Tessellations
Abstract
Cycloarenes are a particular category of polycyclic aromatic
hydrocarbons that have intrigued the experimental world for decades
owing to the distinctiveness of their atomic and electrical
configurations. They are suitable venues for investigating fundamental
problems of aromaticity, particularly those involving the π-electron
distribution in complex aromatic structures. Cycloarenes have recently
attracted much attention due to their distribution as analogs for
graphene pores. Kekulene is the member of this family that has been
studied the most. For decades, its electrical structure has been a
source of contention. It’s a doughnut-shaped chemical structure of
circularly stacked benzene rings with interesting structural
characteristics that lend themselves to experimental investigations like
π-electron conjugation circuits. To predict their properties,
topological characterization of such structures is required. This paper
discusses two new series of big polycyclic compounds made by
tessellating many kekulene doughnuts to make a hypothetical molecular
belt with multiple cavities
