Abstract
C36 is the most important fullerene cage. In this paper, the structural properties of C36fullerene interacting with glycine radicals are analyzed through the density functional theory. The radical adsorptions result in modifications on the structural properties of the original fullerene. It was found out that the binding of glycine to C36 generated a slightly unstable complex. This indicates that fullerene cages might be unable to form stable bindings to glycine radicals. These results are extremely relevant in order to identify the potential applications of functionalized C36 as drug delivery systems.
Key words: C36, glycine, density functional theory, formation energy, highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) gap.
