Research Publications

Welcome to the Hamilton Research Group at 天美传媒! Research in the group is performed entirely by undergraduates, who learn techniques including organic synthesis, solid-state chemistry, synthesis of air-sensitive materials, column chromatography, self-assembly, coordination chemistry, green chemistry, crystallization, NMR, UV/Vis spectroscopy, IR spectroscopy, and analysis of X-ray crystallographic data.

Our research program has two goals:

Development of more environmentally benign syntheses of porphyrins using a solvent-free approach called mechanochemistry, where reagents are ground together using a mortar and pestle, or an automated ball mill.
Using exo-dentate porphyrins as ligands in metal-organic assembly metal-organic polyhedra and evaluation of their efficacy as catalysts.

Solvent-free Synthesis of Porphyrins

We combine an aldehyde with pyrrole in the presence of an acid catalyst and grind using a mortar and pestle. After a few minutes grinding, a pink crystalline powder forms. Presence of a porphyrin is confirmed by UV/Vis and ¹H NMR spectroscopy. The mechanochemical process can also be automated using a ball-mill. We have shown that the approach works with a variety of aldehydes, giving yields similar to, or in some cases greater than, those available through traditional solution-based methods (Shy et al. Faraday Discuss. 2014, 170, 59-69). We are currently working on expanding the approach to include aldehydes with bulky R-groups, mixed-aldehyde syntheses, and synthesis of di-substituted porphyrins.
