Research Interests

1) Development of “vapoluminescent” compounds that can incorporate volatile organic compounds (VOCs) of interest and change their luminescent behavior. The synthesis of designer ligands capable of accepting targeted VOCs of interest are being conducted in the group for sensor application. 2) Tailoring late transition metal complexes and multidentate ligands for Simultaneous Sensitization of Lanthanide Emissions is the second area of interest. 3) Developing and fundamental understanding of white light-emitting novel materials is another area of research interest in the lab for lighting technology used for general illumination.
