The invention relates to tuned multifunctional linker molecules for charge transport through organic-inorganic composite structures. The problem underlying the present invention is to provide multifunctional linker molecules for tuning the conductivity in nanoparticle-linker assemblies which can be used in the formation of electronic networks and circuits and thin films of nanoparticles. The problem is solved according to the invention by providing a multi-functional linker molecule of the general structure

CON₁-FUNC₁-X-FUNC₂-CON₂

in which X is the central body of the molecule, FUNC₁ and FUNC₂ independently of each other are molecular groups introducing a dipole moment and/or capable of forming intermolecular and/or intramolecular hydrogen bonding networks, and CON₁ and CON₂ independently of each other are molecular groups binding to nanostructured units comprising metal and semiconductor materials.
