Profile: Giacomo Filippini grew up in Fossombrone (Italy). In 2011, he holds a Bachelor's Degree (graduated with 110 cum laude) in Industrial Chemistry from the the University of Bologna (Italy). During the period spent in the research laboratory of Professor Alfredo Ricci, under the supervision of Professor Luca Bernardi, he was involved in the development of enantioselective catalytic strategies promoted by small chiral organic molecules. Later on, he obtained his Master’s degree in Industrial Chemistry  (graduated 110 cum laude, 2012-2013 academic year) from the University of Bologna (Italy). Specifically, in the laboratory of Professor Paolo Righi, under the supervision of Professor Giorgio Bencivenni, he studied the reactivity of α,β-unsaturated ketones using aminocatalytic strategies. In November 2013, he joined the group of Prof. Paolo Melchiorre at ICIQ in Tarragona (Spain), where he undertook his doctoral studies. The main scientific objective of his doctoral research was to employ and combine two powerful fields of molecule activation, photochemistry and organocatalysis, to efficiently realize new carbon-carbon bond forming transformations in an environmentally friendly way. In 2015, he had the opportunity to join the group of Prof. Oliver Kappe at the University of Graz (Austria) for a research stay. In particular, he was involved in the development of photo-organocatalytic transformations under flow conditions. This collaboration provided him the possibility to learn a powerful synthetic methodology - flow chemistry - that has found many applications also in industrial processes. At the end of 2017, he successfully defended his PhD thesis (graduated cum laude, 2017-2018 academic year) and went on to take up a postdoctoral fellowship in the Carbon Nanotechnology Group headed by Professor Maurizio Prato at the University of Trieste. During the period spent in the research laboratory of Professor Maurizio Prato, he worked on the development of new catalytic organic transformations. In particular, he was involved in the design, production and characterization of new carbon-based nano-organocatalytic systems, namely carbon nitrides and carbon dots. In April 2021, he became a Research Fellow (RTD-a) at the Department of Chemical and Pharmaceutical Sciences (DSCF) of the University of Trieste. Then, in October 2023, he joined the same Departement as an Assistant Professor (RTD-b). In Trieste, his research activity is focused on the design and development of novel catalytic organic transformations which address unsolved problems in synthetic chemistry.

 2. Carbon Dots as Nano-Organocatalysts: Carbon nanodots (CDs) are photo-active carbon-based nanoparticles with sizes below 10 nm. Generally, CDs consist of carbon cores that are surrounded by shells containing numerous polar groups such as carboxylic acids, alcohols, and amines. Our research is focused on the study of CDs synthesis, characterization and modification for their use as (photo)catalysts in organic chemistry.

 3. Catalysis Based on 2D-Materials: Metal-free 2D nanomaterials possess high appeal due to their improved cost-effectiveness and lower toxicity with respect to many inorganic structures. The outstanding electronic characteristics of some metal-free 2D semiconductors have projected them into the world of organic synthesis, where they can function as catalysts to drive the sustainable synthesis of high-value organic molecules.
