Description of current projects

Single molecule insights into photophysics of organic semiconductors  (Nicole Quist, Mark Li, Ryan Tollefsen)

Collaborations: Prof. J. E. Anthony (Dept. of Chemistry, University of Kentucky), Prof. R. J.  Twieg (Dept. of Chemistry, Kent State University), Prof. M. Haley (Dept. of Chemistry, University of Oregon)

This project involves exploring photophysics of various organic semiconductor molecules and their donor-acceptor combinations from bulk films to a single-molecule level. The goal of the project is to understand how molecular structure and nanoscale environment affect various properties and processes such as molecular orientation, chemical reactions with oxygen, and energy and charge transfer.

Sustainable organic semiconductor materials  (Greg Giesbers, Jonathan van Schenck, Alex Quinn)

Collaborations: Prof. S. Robinson (Dept. of Forestry, Oregon State University), Prof. V. Remcho (Dept. of Chemistry, Oregon State University)

This project involves exploring optical and optoelectronic properties of non-traditional organic materials. Examples of these include stable, sustainable pigments derived from wood-eating fungi, in collaboration with OSU Forestry.  

Exciton and polariton dynamics in organic semiconductors  (Jonathan van Schenck, Greg Giesbers, Michael Trumbull)

Collaborations: Prof. J. E. Anthony (Dept. of Chemistry, University of Kentucky), Prof. L. Cheng (Dept. of EECS, Oregon State University)

This project involves probing time-resolved dynamics of excited states in various organic crystalline materials and in their microcavities and other resonant structures. The goal of this project is to understand how intermolecular interactions affect exciton dynamics and coupling to the cavity or plasmonic modes.  

Innate response of wild bees to visual stimulus   (Oksana Ostroverkhova)

Collaborations: Prof. S. Rao (Entomology, University of Minnesota)

In this project, we quantify response of native (wild) bees to visual stimuli with various fluorescence and reflection spectra. Field studies are combined with optical characterization of bee traps and theoretical modeling.
