In this work we present a simple, fast and robust method to create a polifunctional surfaces. Glass substrates were modified by two ways with the aim to anchor a novel [pentacarbonyl(phenyl-1,4diethynylmethoxy)]-tungsten(0) (DMCF-W) (Scheme 1). The variety of functional groups of that compound, provide different reactive centers for broad kind of molecules. The transition metal of Fischer Carbene Complex was used like a reducing agent to be able produce gold nanoparticles (AuNp) on surface. Recently in our laboratory was demonstrated the chemical interaction between AuNp and heterocyclic pseudoaromatic compounds 3H-1,2-dithiole-3-thiones as passivants agents*(Scheme 2). The strong interaction between 3H-1,2-dithiole- 3-thiones (thiones) and metal surfaces could be explained by their resonance structures in the ground state. These heterocyclic compounds were used in this work as probe molecule to interact with AuNp on surface.
