Photon-gated electron transfer in two-component self-assembled monolayers
Article Abstract:
A two-component self-assembled monolayer (SAM) consisting of 99:1 cis-p-(C6H5)N=N(C6H4)O(CH2)11SH and trans-p,p-Fc(C6H4)N=N(C6H4)(CH2)4SH(Fc = C5H4FeC5H5) was formed from redox and photoactive azobenzene alkanethiols adsorbed onto an Au substrate to examine the electron transfer in this SAM. Results showed that the film porosity was increased by the cis-trans azobenzene isomerization within the monolayer. It was also found that the electron transfer in SAM can be regulated by photochemically controlling the film structure and free volume.

Electron transmission through self-assembled monolayers
Article Abstract:
A study was conducted to analyze electron transmission through a series of self-assembled monolayer films. An iterative Green's function technique with absorbing boundary conditions was utilized to carry out the analysis. Results indicated the presence of headgroups that produce asymmetric transmission effects. Findings also showed that the molecular configuration in thin films is the most critical factor in determining the tunneling matrix element.
