The Clar and Fries Structure of Fullerenes
Presented by Dr. Elizabeth HARTUNG
Type: Oral presentation
A fullerene is a plane trivalent graph with pentagonal and hexagonal faces and is designed to model carbon molecules. The Fries number is the maximum number of benzene faces, or conjugated 6-circuits. The Clar number is the maximum number of independent benzene faces. These two parameters are linked to the stability of the molecule. We will discuss the structure of a fullerene with respect to these two parameters. In particular, we develop Fries chains, an analog to Clar chains, which were previously introduced by the authors. This is joint work with Jack Graver.
