Recently, much work has been done in developing metal-organic frameworks (MOFs) that are photoactive for many applications including photocatalytic oxidation. NU-1000 is of partciular interest due to the ability of the 1,3,6,8-tetrakis( p-benzoicacid)pyrene (H<sub>4</sub>TBAPy) linker to generate singlet oxygen upon exposure to UV or blue light, and its large (3.1 nm) pores, that allow larger substrates to diffuse in. However, the ability of the pyrene moiety to absorb longer wavelengths of light and produce single oxygen efficiently is limited in its unpertubed state. Herein, various strategies to enhance the efficiency of singlet oxygen generation through H<sub>4</sub>TBAPy linker modification and absorption of the entire spectrum of visible light through post-synthetic incorporation of co-photosensitizers will be discussed. Through simple MOF modifications, photocatalytic rate enhancement of more than an order of magnitude has been acheieved for the photocatalytic degradation of sulfur mustard under military relevant conditions over NU-1000.
