The Chemical and Electronic Structure of Metal/Conjugated Polymer Interfaces : A Joint Theoretical and Experimental Study

• We investigate the interface between aluminum and several prototypical conjugaced systems wich a combined experimental and theoretical approach. The experiments consist of following the evolution of the polymer surface during the early stages of aluminum deposition, with X-ray and Ultraviolet Photoe!ectron Spectroscopies (XPS, UPS). In parallel, we perform quantum chemical calculacions on mode! oligomer systems interacting with one to four Al atoms. Aluminum is found to internet strongly with the polymer chain. Al·carbon covalenc boods an: formed along the polymer backbone; the chain geomeuy is deeply modified and the π electron conjugation can be dramatically reduced.
