Abstract

For the development of molecular electronics, it is of great importance to elucidate the nature of the electric contact between metal electrodes and anchoring groups. Thiols are the most commonly used group to be adsorbed on a gold electrode, while other functional groups have been recently attracting much attention as the candidate of an alternative anchoring group. Here, we present the synthesis of tripodal anchor units bearing pyridyl, amino, and selenol groups and the characterization of their monolayers. The monolayers on a gold surface were prepared by immersing Au/mica substrate in their CH2Cl2 solution for 12 h. These monolayers were characterized by CV and XPS measurements. The conductance measurement of molecules having tripodal anchor units at both terminal positions were investigated by STM break junction.
