Current research

Our main research interests are the design, synthesis, characterization, self-assembly and applications of π-conjugated molecular architectures for solar energy conversion and the development of novel photochemical reactions. 


Please check the following article to find out the main topic we are currently working on: Cappelletti, D.; Barbieri, M.; Aliprandi, A.; Maggini, M.; Đorđević, L.*; "Self-assembled π-conjugated chromophores: preparation of one- and two-dimensional nanostructures and their use in photocatalysis" Nanoscale, 2024, 16, 9153-9168. https://doi.org/10.1039/D4NR00383G (PDF).


We also like to develop novel photocatalytic systems for homo- and hetero-geneous production of solar fuels or commodity chemicals.

Previous post-doctoral research 

From 2018 to 2022w, Luka moved was at Northwestern University (USA), where he was a postdoctoral research associate funded by the U.S. Department of Energy within a fellowship at the Center for Bio-inspired Energy Sciences. The research here was focused on novel supramolecular systems for photocatalysis and developing new photocatalytic reactions (Nature Chemistry 2022, 14, 1007;  J. Am. Chem. Soc. 2022, 144, 3127; J. Am. Chem. Soc. 2021, 143, 8000;  J. Am. Chem. Soc. 2021, 143, 18131). The work on photocatalytic systems was highly ranked by the Lincean Academy and, as a result Luka was awarded the "2020 Stanislao Cannizzaro International Prize in Chemistry and Physical Chemistry". More recently, the work and future vision on photocatalysis were highly ranked by independent and international peer review groups, and as a result Luka was selected as the "2021 Dream Chemistry Award Top 5" and "2022 European Young Chemists' Award Finalist"

During Luka's postdoc at the Universities of Trieste (IT) and Cardiff (UK) (2016-2018), he initiated new lines of inquiry through the preparation and characterization of novel heteroatom-doped molecules and nanomaterials. Luka prepared oxygen-doped polycyclic aromatic hydrocarbons, investigated their optoelectronic and redox properties, and prepared mixed valence conductive crystals (Angew. Chem. Int. Ed. 2020, 59, 4106;  Org. Lett. 2020, 22, 4283).
During this period, Luka also prepared nitrogen-doped carbon-based dots and investigated ways to tune their properties (Nat. Nanotechol. 2022, 17, 112-130;  Nat. Protoc. 2019, 14; 2931;  Adv. Sci. 2021, 2100125). For example, he prepared nanoparticles that could be used as templates for formation of chiral supramolecular polymers (Nat. Commun. 2018, 9 (1), 3442) or to arrange multichromophoric arrays (Angew. Chem. Int. Ed. 2020, 59, 12779;  Mater. Chem. Front. 2020, 4, 3640). This work was also the basis of the ERC Advanced Grant awarded to Prof. Prato in 2019 ("e-DOTS"). Moreover, the work on heteroatom-doped carbon nanoparticles was highly ranked in terms of scientific quality and as a result I was awarded the prestigious 2018 Primo Levi Award and the "2020 Giacomo Ciamician medal" (Angew. Chem. Int. Ed. 2021, 60 (1), 313). During this period, Luka also supervised a PhD student, whose work was recognized as main author in Angewantde Chemie and Nature Communications articles.

 

Previous Ph.D. research 

In 2016, Luka obtained my PhD degree in Chemical and Pharmaceutical Sciences and Technologies, under the supervision of Prof. Davide Bonifazi. The PhD research work has contributed to (nano)structuration of organic nanomaterials in solution and surfaces (J. Am. Chem. Soc. 2015, 137, 8150–8160;  Phys. Chem. Chem. Phys. 2016, 18, 11858–1186). Luka proposed, developed, and demonstrated new methods for transferring precise supramolecular nanostructures from solutions to surfaces based on organic and supramolecular chemistries. The research work has successfully demonstrated that bottom-up nano-structuration approach is an alternative to conventional top-down methods. As a result of this work, Luka received the 2017 CINMPIS award for best PhD dissertation (IT). During the PhD, he also spent one year as visiting scholar at the Broad Institute of MIT and Harvard (USA), and his work there has led to one research article and two patents.
