Functionalizing Graphene Surfaces with Precise Dye Absorbed Oxygen Deposition

Abstract

This thesis studies the properties found in graphene and combines them with the potential of increased responsivity due the addition of dyes which could allow for more efficient and effective optoelectronics. Here, we theorize the bonding between 2,4,6-trichloro-1,3,5-triazine (Cyanuric Chloride) and Graphene Oxide to allow the bonding of 1-amino-2-methylanthraquinone (Disperse Orange 11) to occur. With this bond occurrence, future studies can investigate the local bonding of such organic bonds onto graphene oxide for the use in micro and nanotechnology. The specific design is as follows. Cyanuric Chloride is covalently bonded to the oxygen of the Graphene Oxide sample. Disperse Orange 11 is then added to the mixture allowing for the covalent bonding of the dye. This sample is then tested with a series of spectroscopy instruments including a UV-Vis machine and an XPS machine as well as height testing with an AFM to determine the success of the dye bonding.
