Previously, we demonstrated that the condensation of aryloxybenzene derivatives with hydrosilanes, catalyzed by B(C6F5)3, leads to silicone-modified aromatics. We now demonstrate, surprisingly in light of the size of the catalyst, that the reaction can also be induced on the surface of ITO.ITO surfaces were first modified with a hydrosilane coupling agent using traditional methods. Exposure of the ITO surface to the arylamine in the presence of low quantities of B(C6F5)3led to a surface to which was tethered the amine. A combination of CA, SEM and AFM images demonstrated the modification had occurred. In addition, AFM also demonstrated the presence of particles chemisorbed on the surface ranging in size from about 20-40 nm in diameter. EDX analysis of the well-defined organic nanoparticles confirmed the presence of nitrogen, thereby indicating amines.The potential of these materials to affect electron transport in the region of the ITO interface will be discussed.
