Luminescent Metal-Organic Frameworks

Metal-organic frameworks (MOFs), porous materials composed of metal ions and organic linkers, have broad applications in separation, small molecule storage, and catalysis. Luminescent metalorganic frameworks (LMOFs) hold great potential in the development of sensors, and, with their relatively straightforward syntheses that produce predictable, homogeneous, extended structures, should result in good sensor-to-sensor reproducibility and uniform response. In addition, subtle differences in overall LMOF structure, metal ion coordination, pore surfaces, and host-guest interactions within pores should have significant impact on observed photoluminescence and provide numerous strategies for analyte detection. Highlighted here is the development of LMOFs composed of zinc or zirconium ions that incorporate luminescent osmium complexes into the framework structure and the excitation and emission spectra of these materials in the presence of small molecules of varying polari

Incorporation of Luminescent Osmium Complexes into Metal-Organic Frameworks: Optimization of Osmium Complex Synthesis and Effect of MOF Structure on Complex Inclusion and Emission

Metal-Organic Frameworks (MOFs) are materials that contain metal centers coordinated by organic molecules that form an extended, porous lattice. These MOFs are of interest in the field of sensing for their unique properties such as high stability, high surface area, high crystallinity, and ability to perform small molecule exchange. Luminescent metal-organic frameworks (LMOFs) are of specific interest since they contain the potential to detect odorless volatile organic compounds (VOCs) via adsorption into the porous framework. Luminescent properties can be imparted to MOFs in several ways. This project focused on the inclusion of a luminescent osmium complex into the MOF scaffold. The optimization of the osmium complex synthesis will be detailed. Doping of several MOF systems with the luminescent osmium complex was explored and the resulting emission spectra from these studies will be presented
