Information from Chemfinder (http://chemfinder.cambridgesoft.com). SI units were used where possible. Unless otherwise stated, standard conditions were used.

Coronene is an aromatic molecule consisting of 7 benzene rings. It is especially stable since the electrons in this system are not fixed in one place. They can move all around the molecule because it's a conjugated system.

Coronene - Wikipedia, the free encyclopedia (534 words)
	Coronene is produced in the petroleum refining process of hydrocracking, where it can domerize to a twenty-five ring PAH.
	In the latter case the most stable structure for coronene has only the three isolated outer sextets as fully aromatic although superaromaticity would still be possible when these sextets are able to migrate into the next ring.
	In this geometry the stacks of coronene disks are aligned with the length of the tube.
