Research Interests

Barybin Research Group Webpage

Our research program is at the interface of inorganic, coordination, organic, and materials branches of chemistry.  It largely involves development of organometallic and inorganic synthetic methodologies and studies of electron delocalization and transport in electron-rich organometallics.  For example, we have recently devised strategies for incorporating the electronically unusual azulenic motif (a carbon framework involving fused 5- and 7-membered rings) into molecular and supramolecular hybrid metal/organic ensembles relevant for applications in molecular electronics and nanotechnology.  We employ a variety of theoretical, analytical, and spectroscopic tools to assess physicochemical properties of the new compounds/materials established in our laboratory as well as guide our synthetic efforts.  Among these methods are multinuclear and multidimensional NMR (including NMR of paramagnetic molecules and ions), organic and organometallic electrochemistry, single crystal X-ray crystallography, electronic and vibrational spectroscopies, Density Functional Theory calculations, and various surface and imaging techniques.  The current projects can be grouped into the following categories:

 

• Azulene-based organometallics: toward new hybrid metal/organic compounds and materials with unusual electron transport and optical properties

(e.g., J. Am. Chem. Soc. 2006, 128, 2300-2309)

 

 

• Reversible electron-rich electrochromic systems, compact molecular electron reservoirs

(e.g., Organometallics 2004, 23, 2927-2938)

 

 

• Designed organic surfaces for electronics or sensing applications
