Abstract
Ordered ultra-thin films of poly(2,5-diheptyl-p-phenylene) (or DHPPP) have been formed upon ordered substrates consisting of parallel chains of polytetrafluoroethylene (PTFE) on silicon (100) wafers. The electr onic structure of the ordered DHPPP has been studied by angle-resolved ultraviolet photoelectron spectroscopy (ARUPS). The results indicate that the aliphatic side groups of the DHPPP molecules are ordered para llel to the PTFE chains, resulting in the PPP backbone lying at an ang le of roughly 90 degrees to the PTFE chains.
