Abstract

We compare scanning tunneling microscopy (STM) imaging with single-molecule conductive atomic force microscopy (C-AFM) measurements by probing a series of structurally related thiol-terminated oligo (phenylenevinylene) s (OPVs) designed to have unique charge-transport signatures. When one or two methylene spacers are inserted between the thiol points of attachment and the OPV core, a systematic reduction in the ...
