Abstract | Currently, fossil fuels including coal, petroleum and natural gas, account for over 80% of worldwide energy usage. Combustion products from these energy systems make a significant contribution to greenhouse gases and represent a significant environmental threat. To mitigate the threat of greenhouse gas emission, catalysts capable of both capturing and reducing greenhouse gases, such as CO2, are of critical importance. A particularly attractive class of CO2 photoreduction catalyst involve Re(I)(CO)3(2,2’-bipyridine)L complexes where L represents a photoreleasable ligand. Coupling this type of catalyst with a porous metal-organic framework (MOF), capable of sequestering high concentrations of CO2, represents a significant advance in technology for CO2 mitigation. Here we describe the synthesis, optical properties, and solid state structural characterization of various Re(I)(CO)3(2,2’-bipyridine)L complexes encapsulated within the Zn(II)-trimesic acid based MOF, USF2. Effects of encapsulation on the Re(I) complex will be discussed as well as the consequences of confinement of the overall catalytic mechanism. |
