The quality of metal-organic frameworks (MOFs) and the mechanisms of  post synthetic modification of the framework  are important for extending their applications. We applied single-molecule fluorescence methods to characterize the dynamic mechanisms of MOFs as they catalyze reactions. Since some MOFs produce luminescence and the lifetime of the luminescence is strongly dependent on the environment of the MOF; therefore changes in the organic linker or the solvent in the framework the network will cause changes to the framework which are reflected in the luminescence lifetime and luminescence spectrum of the MOF.  So far we have demonstrated multiple pillar exchange steps in a zinc-porphyrin framework (PPF) and initiated luminescence characterization, of the PPFs and an indium-pyrene frameworks.
