The coumarin phosphorus-containing derivatives are well known for their various biological activities and are extensively used in medicine, as pesticides etc. These properties have provoked the research interests of the Group of Organic Synthesis and NMR spectroscopy towards the synthesis of phosphorus-containing coumarin derivatives as well to a detailed investigation on their chemical behaviour and properties. On the other hand their research interests range from the development of new class dyes and pigments, including methods of organometallic chemistry, to the chemistry and physics of small molecules, graphenes and biosynthetic hybrids.
