IRTG 2991 - International Research Training Group 2991

Welcome

IRTG 2991 is an international and interdisciplinary, knowledge-driven research and training program on innovative supramolecular functional materials with photoluminescent properties. In close collaboration between researchers at Julius-Maximilians-University Würzburg (JMU) and the Indian Institute of Science Education and Research Thiruvananthapuram (IISER TVM) the team conducts cutting edge research projects on fluorescent, phosphorescent and higher complexity luminescent materials by making use of smart supramolecular matrices. The research program includes synthetic organic and biomolecular chemistry, physical and theoretical chemistry for structure and function elucidation, and applications in bioimaging and OLED devices.
