Supramolecular Chemistry Research Group

Group Leader
Engin U. Akkaya

Research Interest
Fluorescent Molecular Sensors, Molecular Logic Gates, Dye-Sensitized Solar Cells, Photodynamic Therapy

Research Overview
While the majority of chemical processes are no doubt driven by interactions between individual molecules, more complex structures, formed through the assembly of large molecular subunits, dominate the biological scape and display a number of curious properties. Dr. Akkaya’s group characterizes the behavior of such complex molecular assemblies and their interactions, with emphasis on the optical behaviors exhibited by fluorescent dyes. These molecules can be used as molecular sensors, solar cell sensitizer dyes, biological markers and therapeutic agents in photodynamic treatments.
