Abstract
Recently, organic-inorganic hybrid materials, such as coordination polymers and metal-organic frameworks (MOFs), have seen increased research efforts due to their potential applications from electronics to separation sciences. In coordination chemistry, organic ligands are used to prepare coordination complexes, by binding with metal centers. Structure of organic ligands can play significant roles in designing the resulting properties. The ligands vary in size, shape, and functional groups. One of the most commonly used types of ligands in preparing coordination polymers and MOFs are carboxylic acids. In our laboratory, we are interested in investigating contrast between organic-inorganic hybrid materials prepared from known carboxylic acid ligands and their thiocarboxylic acid analogue. Sulfur is an intriguing and logical element to replace oxygen in carboxylic acids, because it has similar binding modes to metal centers as oxygen, but exhibit distinct reactivities and structures of its own. Such differences include bond angles, bond lengths, and polarity. In this study, novel thiocarboxylate and thiocarbamate ligands were prepared and characterized using NMR, IR, and MS. In addition, known and novel MOFs were also prepared to study unique properties arising from the use of sulfur.
