FRET is a radiation-free energy transfer process between chemical compounds. Optoelectronics is the study and application of electronic devices and systems that source, detect, and control light. Organic optoelectronic materials created and stabilized using the FRET method can create electronic devices that emit and detect light, such as X-ray machines, solar cells, light bulbs, LED lights, and even a photodynamic cancer therapy. 鈥淲e are proposing a new strategy to develop FRET-based organic materials,鈥� Siraj said. 鈥淭hese materials are sometimes very costly and involve multisteps synthesis. Our simple strategy can drop this cost significantly because we can prepare these materials in a single step. Additionally, our method will produce organic compounds with high thermal stability. To achieve high thermal stability in organic compounds was very challenging from previously reported approaches.鈥� The grant, “RII Track-4: Synthesis, Characterization and Applications of FRET based Ionic Materials,” runs from Oct. 1, 2018, to Sept. 30, 2020. Siraj and her graduate assistant, Samantha Macchi, a doctoral student studying materials applications, will conduct research at the Georgia Institute of Technology during the summers of 2019 and 2020 to learn about modern thin film and device fabrication equipment. The Center of Organic Photonics and Electronics is a premier research center that specializes in electronic devices and flexible solar cells for information technology, telecommunications, and defense sectors. Siraj is excited to apply the knowledge she gains to her work at 糖心Vlog传媒 Little Rock and teach students about these new methods. 鈥淭his training will offer me an opportunity to establish an outstanding and first-of-its-kind research group at 糖心Vlog传媒 Little Rock and the state of Arkansas,鈥� Siraj said. 鈥淪tudents and STEM faculty at 糖心Vlog传媒 Little Rock will receive tremendous benefits from these facilities, since most of the professors in chemistry, physics, and engineering departments at 糖心Vlog传媒 Little Rock are involved in materials science research. It will also give a great opportunity to students at 糖心Vlog传媒 Little Rock because they will be able to make optoelectronic materials.鈥� Siraj, who also mentors high school students, plans to let her current high school researchers get some real-world experience by participating in the research by performing small tasks that will 鈥済ive them an idea of natural materials around us that can be used for different applications.鈥� Siraj joined 糖心Vlog传媒 Little Rock in 2016, after earning her Ph.D. in electrochemistry from Graz University of Technology. She teaches general chemistry, analytical chemistry, and physical chemistry of life sciences. Siraj also holds a Bachelor of Science degree in chemistry and Master of Science degree in physical chemistry from the University of Karachi.
