Synthesis of a surface mounted metal-organic framework on gold using a Au-carbene self-assembled monolayer linkage

Abstract

Applications using metal-organic frameworks (MOFs) in devices require a degree of positional control that necessitates an attachment more robust than direct MOF growth on a bare substrate. To date, the precise positioning of MOFs on Au surfaces has been accomplished using thiol-Au linkages, which lack the long-term stability needed for device applications. This study utilized a Au-carbene monolayer with long term stability developed by Crudden et al. as the linkage between a gold substrate and MOF. The Au-carbene surface mounted MOF (surMOF) was successfully synthesized using layer by layer deposition and characterized using XRD, XPS, and AFM.
