Research Interests:
I am interested in synthesizing and studying new rhodium
compounds that exhibit luminescence. These compounds are of
interest as possible reaction catalysts, both photochemical and
electrochemical, as emissive DNA (nucleotide base) labels, and as
probes of DNA structure. We have synthesized several new complexes
and are currently characterizing their luminescence.
Research Projects Available:
- Investigation of the luminescence, absorption, and
electrochemistry of our current cis-[Rh(bpy)2(SS)]2+ systems, where
bpy = 2,2'-bipyridine and SS = dialkyldithiocarbamates.
- Luminescence spectroscopy studies of cis-[Rh(bpy)2(CN)2]+ to
determine if the emission is pH dependent.
- The synthesis of cis-[Rh(bpy)2(PP)]3+ complexes.The challenge
here will be to find the best chelate lengtha four, five, or six
membered ringand an alkyl group on the phosphine that will allow us
to determine purity by 1H and 13C-NMR.
- The synthesis of new cis-[Rh(bpy)2(SS)]+ systems, where SS =
substituted 1,1- and 1,2-dithiolates. This will involve synthesis
and purification of the ligands prior to synthesizing the metal
compounds.
- The synthesis of the cis-[Rh(bpy)2(bpp)]3+ complex where bpp =
2,3'-bis(2-pyridyl)pyrazinea ligand that can bridge two metal
centers. By attaching a [Ru(bpy)2]2+ unit to the bpp bridge we
could explore intramolecular excited state electron transfer
chemistry between the rhodium and ruthenium.
