Abstract

Metal-organic frameworks (MOFs), porous materials composed of metal ions and organic linkers, have broad applications in separation, small molecule storage, and catalysis. Luminescent metal-organic 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, which shows promise for the detection of alcohols. Highlighted here is the development of LMOFs composed of zinc ions that incorporate luminescent osmium complex into the framework structure and the excitation and emission spectra of these materials in the presence of small molecules of varying polarity. The effect of the organic linkers within the MOF scaffold on the luminescence osmium was also studied.
