Coronene(cas 191-07-1) also known as superbenzene is a polycyclic aromatic hydrocarbon (PAH) comprising six peri-fused benzene rings.
It is a yellow material that dissolves in common solvents including benzene, toluene, and dichloromethane. Its solutions emit blue light fluorescence under UV light. It has been used as a solvent probe, similar to pyrene.

We report studies of the correlated excited states of coronene and substituted
coronene within the Pariser⁻Parr⁻Pople (PPP) correlated π -electron model
employing the symmetry-adapted density matrix renormalization group technique.
These polynuclear aromatic hydrocarbons can be considered as graphene
nanoflakes. We review their electronic structures utilizing a new symmetry
adaptation scheme that exploits electron-hole symmetry, spin-inversion symmetry,
and end-to-end interchange symmetry. The study of the electronic structures
sheds light on the electron correlation effects in these finite-size graphene
analogues, which diminishes going from one-dimensional to higher-dimensional
systems, yet is significant within these finite graphene derivatives.
