Nanostructures are likely to become primary components of future electronic devices. Self assembled molecular electronics is a route to achieve this goal. One central issue in molecular electronics deals with charge transport across molecular elements. In this letter we present a hybrid system sensitive to the coupling and consequently to charge or energy transfer through organic molecules. Our system uses gold nanoparticles coupled through organic molecules layers to type II superconductor. We correlate the organic capping ligands of the gold nanoparticles with the vortices pinning efficiency. This sensitive phenomenon distinguishes between different organic molecules coupling efficiency.
