Abstract

Conjugated polymers have emerged as viable electronic materials for numerous applications. In the context of polymer electronic devices, it is of critical importance to understand the nature of the electronic structure of the polymer surface and the interface with metals. It has been shown that, especially for conjugated polymers, photoelectron spectroscopy provides a maximum amount of both chemical and electronic structural information in one (type of) measurement. An overview of some details of the early stages of interface formation with metals on the surfaces of conjugated polymers and model molecular solids, especially in connection with polymer-based LED devices, is presented. Materials involved include poly(p-phenylenevinylene), or PPV, as well as a series of substituted PPV’s, and a diphenylpolyene molecule, namely α, ω-diphenyltetradecaheptaene. Some general trends in the behaviour of light-metal atoms on the clean surfaces of conjugated polymers will be pointed out. Finally, a series of new results will be discussed, one in limited detail, the others more briefly, in order to indicate some recent new developments in this area.
