摘要：

Using diamine as anchoring group, the self-assembled monolayers(SAMs) based on oligo(phenyleneethynylene)s(OPEs) and cruciform OPEs with an extended tetrathiafulvalene(TTF)(OPE3 and OPE3-TTF)were successfully formed on the Au substrate. The Uniformity and stability of SAMs were confirmed through cyclic voltammetry(CV) and electrochemical reductive desorption. The investigation of transport properties of SAMs was achieved by conducting-probe atomic force microscopy(CP-AFM) with both Au and Pt tips. The results indicated that the conductance of OPE3-TTF was 17 and 46 times that of OPE3 for Au and Pt tips, respectively. Theoretical calculations are qualitatively consistent with the experimental results, suggesting that the diamine as anchoring group has a great potential in molecular electronics.
