Phenylene ethynylene oligomers have been studied as candidates for molecular electronic devices using scanning tunneling microscopy.@footnote 1-6@ These molecules were inserted into host alkanethiolate self-assembled monolayers for isolation and individual addressability. Many different hypotheses and theoretical predictions have been put forth to describe conductance switching.3-4 We have tested several of these through variations in the molecular design of our molecular switches and have concluded that the only mechanism consistent with all the switching data are that changes in the molecule-substrate bond hybridization leads to the observed conductance changes. @FootnoteText@ @footnote 1@Donhauser, Z.
