Graphene/Neutral red dye composite has been synthesized by covalent binding of dye molecules to the basal plane of graphene through diazonium chemistry approach. Resulting nanosystem was studied by synchrotron-based high-resolution X-ray photoelectron spectroscopy (HR-XPS), photoemission electron microscopy (PEEM), and scanning tunneling microscopy (STM). Obtained data verifies high stability of the nanostructure even after exposure of the samples into ultrasonic bath and annealing in ultrahigh vacuum conditions. This work was supported by RAS, RFBR (Grant Nos. 17-02-01139, 17-02-01291) and Minobrnauki of Russia (Project 3.3161.2017/4.6).
