3 Aluminum, sodium, calcium and rubidium on a diphenyl-polyene 

Some aspects of the electronic structure of DP 7 need to be mentioned in order to facilitate the discussion of the metallization. The valence electronic structure of DP7, obtained with Hell 

In Fig. 7.10, is shown a portion of the C(ls) XPS spectrum for /ramj-polyacetylene, DP7, and condensed (molecular solid) benzene. The main C(ls) peaks are not displayed, but only the relatively weak satellite features that appear on their high binding energy side of the 

In contrast to aluminum, where covalent reactions at the interface are observed, and a metal over-layer is then formed, it is possible to deposit sodium on the DP7 system without building a metal
