摘要

Conductance across a metal| molecule| metal junction is strongly influenced by the molecule– substrate contacts, and for a given molecular structure, multiple conductance values are frequently observed and ascribed to distinct binding modes of the contact at each of the molecular termini. Conjugated molecules containing a trimethylsilylethynyl terminus,– CCSiMe3 give exclusively a single conductance value in I (s) measurements on gold ...
