An ability to control nanoscale morphology and molecular organization in organic semiconducting polymer thin films is an important prerequisite for enhancing efficiency of organic thin-film devices including organic light-emitting and photovoltaic devices. A promising approach toward such polymer films is surface-confined polymerization of small-molecule monomers. In this presentation, we describe development of an efficient method to prepare bulk semiconducting polymer thin films as well as nanoscale organic/inorganic hybrid materials utilizing surface-confined Kumada catalyst transfer polymerization. Extensive structural studies of such materials using X-ray and neutron scattering methods revealed detailed information on their molecular organization and bulk morphology, and enabled further optimization of the polymerization protocol. Overall, the surface-confined polymerization provided an efficient tool to prepare structurally defined and highly stable semiconducting polymer films and hybrid nanoscale systems with tunable spectroscopic characteristics and electronic properties.
