Abstract
Metal Organic Frameworks (MOFs) are of major interest in organic chemistry today for their microporous properties, and their potential applications in catalysis, separations, and chemical sensing. Fluorescent MOFs are relatively rare but are attracting attention because of their optical properties. In these applications, MOFs can serve as quantative measuring devices of molecules within the microporous gaps by conversion of light. We are interested in synthesizing fluorescent MOFs based on fluorescent ligands, and more specifically, tetraphenylethylene (TPE) derivatives. For example, a polytopic TPE ligand (1) has been synthesized from 3-pyridyl boronic acid and tetrakis(4-bromo)phenylethylene via Suzuki coupling. This gives a highly conjugated and relatively planar molecule that has four potential binding sights to metal centers within a MOF. The crystal structure of this compound has been obtained, and incorporation of this ligand into new MOFs will be discussed.
