The cobaloxime catalysts are sensitized by different meso-pyridyl boron dipyrromethene (BODIPY) chromophores, bearing either two bromo- or iodo-substituents on the BODIPY core. The pyridine linker between the BODIPY and cobaloxime is further modified by a methyl substituent on the pyridine, influencing the stability and electronic properties of the cobaloxime catalyst and thus the photocatalytic efficiency of each system. Four cobaloxime catalyst complexes and three novel BODIPY chromophores are synthesized and characterized by absorption, fluorescence, infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, and electrochemistry. Crystal structures for the BODIPY-cobaloxime complexes 2 and 3 are presented. In contrast to the photocatalytically inactive, nonhalogenated reference complex 1, the four newly reported molecules are active for photocatalytic hydrogen evolution, with a maximum turnover number (TON) of 30.9 mol equiv of H2 per catalyst for the meso-methylpyridyl 2,6-diiodo BODIPY-sensitized cobaloxime complex 5. We conclude that accessing the photoexcited triplet state of the BODIPY chromophore by introducing heavy atoms (i.e., bromine or iodine) is necessary for efficient electron transfer in this system, enabling catalytic hydrogen generation. In addition, relatively electron-donating pyridyl linkers improve the stability of the complex, increasing the overall TON for hydrogen production.}, number={9}, journal={INORGANIC CHEMISTRY}, publisher={American Chemical Society (ACS)}, author={Bartelmess, Juergen and Francis, Aaron J. and El Roz, Karim A. and Castellano, Felix N. and Weare, Walter W. and Sommer, Roger D.}, year={2014}, month={May}, pages={4527–4534} } @article{bartelmess_weare_sommer_2013, title={Synthesis, characterization and structural investigation of novel meso-pyridyl BODIPY-cobaloxime complexes}, volume={42}, number={41}, journal={Dalton Transactions (Cambridge, England : 2003)}, author={Bartelmess, J. and Weare, W.

The distyryl substituted precursors for the cationic target molecules presented in this study allow for further functionalization in a variety of ways, and are promising starting materials for further synthetic development of BODIPY dyes. The fluorescent, red-absorbing di- and tri-cationic dyes are well soluble in water and polar organic solvents and offer possibilities for fluorescence marking in biochemistry, photodynamic therapy, chemical sensing and other aqueous applications. The introduction of a pyridine substituent in the meso position of the BODIPY allows for control over fluorescence properties and offers the future possibility for the development of novel coordination complexes. This combination of properties allows these BODIPY derivatives to be possible building blocks for multi-purpose functional materials.}, number={1}, journal={DYES AND PIGMENTS}, author={Bartelmess, Juergen and Weare, Walter W.}, year={2013}, month={Apr}, pages={1–8} }
