Report The aim of my doctoral research is the deeper understanding of the formation of various carbon-R bonds (R= C or B) under photochemical and mechanochemical conditions. Mechanochemistry describes the performance of neat chemical reactions under the impact of mechanical energy, which leads to an enormous reduction of chemical solvents. Further, light produces no additional waste and can therefore be considered as one of the greenest energy sources available making the combination of Mechano- and Photochemistry highly attractive in terms of Green Chemistry. My thesis includes the investigation on a suitable combination of Mechano- and Photochemistry by designing a novel reactor, which meets the emerging requirements and examination the milling parameters.
Through the PR.INT Research School grant, I had the opportunity to visit the laboratory of Dr. Krunoslav Užarević at the Ruder Boskovic Institute in Zagreb, Croatia in June 2023, who is specialized on the design of novel ball mills. Working in his working group offered me the opportunity to investigate various milling parameters by using his custom-made photochemically equipped ball mill. During my two week stay, I was able to compare his photo-mechanochemical set-up equipped with Hg-lamps with our custom-made LED-photoreactor, which helped me in understanding the effect of different light sources and therefore different energies on my model reaction.
In addition, networking with his working group and colleagues has helped to expand my scientific network and opened the opportunities for future scientific collaborations.
