The processibility of conducting polymers remains an important challenge for their widespread adoption in modern electronic devices. The in-situ, electroless polymerization method allows a convenient method for coating a wide variety of substrates with a coating of polymeric material 50-500 nm thick. We have been investigating the use of well defined self-assembled monolayers of coordinate-covalent tethered inorganic chromophores for use as photoswitching organic/inorganic hybrid devices prepared in-situ. In the process we have discovered enhancements in conductivity as high as two orders of magnitude for films prepared on these surfaces. Here we will discuss the factors which control this interfacial effect such as the role of the metal center and ligand environment. While polyaniline has previously been the focus of this research, the extension of these conductivity enhancements for other conducting polymers including PEDOT and polypyrrole will also be presented.
