Titanium-based Organic Frameworks for Chemical Transformations

Varma, R. AND S. Verma. Titanium-based Organic Frameworks for Chemical Transformations. 253rd American Chemical Society (ACS) National Meeting, San Francisco, CA, April 02 - 06, 2017.
Impact/Purpose:
Metal–organic frameworks (MOFs) based on organic bridging ligands are a promising class of highly ordered porous materials1 with potential applications in catalysis, gas storage and photoelectric devices. The availability of external surface of the solid-state catalysts plays an important role on the catalytic prowess in heterogeneous catalytic processes;2 uniformly distributed active sites in MOFs provide an energetic platform for organic transformation. The documented success of MOFs,3 prompted us to seek a sustainable frame work containing electron-rich organic moiety as ligand with an earth-abundant common element. The development of titanium-based organic frameworks provides such a stable MOF with reactive metal nodes as functional moieties. These titanium-based organic frameworks not only form strong bonds with ligands to afford a highly stable structures, but also provide the materials with good photocatalytic activity.4 The utility of highly porous titanium-based organic frameworks will be highlighted in the synthesis of cyclic carbonates, dimethyl carbonates, and dimethyl anilines under visible light including the photocatalytic oxidation of aromatic alcohols.
