Controlling the growth of metal organic nanotubes (MONs) will potentially enhance their applicability in the water purification process. MONs have water selective properties that eliminate contaminants from water. The uniform reorientation of the MONs creates directional flow by allowing water to pass through the selective channels. In order to control the growth of the MONs, a self-assembled monolayer (SAM) was employed on a gold substrate. The SAMs contain a thio (SH) group that attaches to the gold surface and an –OH functionalized ends that has the potential for hydrogen bonding with the MON. Using these functionalized end members of the MON. The nucleation of the MONs on the surface of the SAM was observed using microscopic techniques and provides a foundation for the development of membranes for advanced water purification applications.
