High resolution surface characterization of chromophore-modified graphene

The aim of this work is to understand the surface interactions of Reduced Graphene Oxide (RGO) with a water soluble corrole using graphene as a versatile substrate for sensor devices. Scanning Tunneling Microscopy (STM) and UV-Vis Spectroscopy are employed for understanding the morphology and microstructure of the deposited corrole molecules on RGO at atomic level. Other surface characterization technique like X-Ray Photoelectron Spectroscopy (XPS) is also used for better understanding of the chemical distribution, the molecular environment and the hybridization of the corrole molecules on RGO.
