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.

IRTG 2991 – Good Scientific Practice Workshop

The picture above shows a photograph of the “Lying Stones” that were “discovered” close to Würzburg in the 18^th century. Their story is one of forgery and too much eagerness of scientists to interpret findings in a way that suits their own beliefs.
