Research Description

Description of Research
Prof. Noftle is interested in the synthesis and characterization of new materials which have applications in electronics, optics and medicine. These substances have the potential to be utilized as charge storage media, light-emitting diodes, metal uptake and release agents, trace metal ion sensors, and drug delivery agents. One project is concerned with the preparation and properties of new thiophene compounds which form electrically conducting polymers while another (in collaboration with Prof. Lachgar) involves the synthesis of new metal-organic  framework materials which may act as high-capacity hydrogen storage agents. A multitude of  techniques are used in our research including infrared, NMR, fluorescence and UV-vis spectroscopy, mass spectrometry, x-ray crystallography, thermal gravimetric analysis, and electrochemistry. Students may become involved in all or any parts of this research.
