hfip cycloisomerizationsCongratulations to our Ph.D. student Alberto Gobbo for his scientific publication entitled “Hydrogen bonding-enabled gold catalysis: ligand effects in gold-catalyzed cycloisomerizations in hexafluoroisopropanol (HFIP)” in ChemComm. Gold catalysis has witnessed immense evolution in recent years, yet it still requires the use of activators to render the common AuCl(L)] complexes catalytically active. Herein, the H-bonding donor properties of hexafluoroisopropanol (HFIP) are utilized for Au–Cl bond activation and the ancillary ligand and counteranion effects on cycloisomerization reactions are showcased in HFIP as solvent. In addition, HFIP is not only a suitable solvent for gold catalysis with [AuCl(L)] complexes, but it also enables catalysis with Brønsted-basic complexes.

niccolai macrogiovaniCongratulations to our Ph.D. student Francesca Niccolai for winning one of the best presentations at Macrogiovani 2022, an event organized by "Associazione Italiana di Scienze e Tecnologie delle Macromolecole" (AIM) in Florence. The title of her presentation was "Next-generation composite polymeric membranes for semi-organic redox flow batteries". Redox flow batteries (RFBs) are promising candidates for large-scale energy storage thanks to their long service lifetimes, relatively low capital costs, and independent scaling of energy and power density. The membrane is a pivotal component of RFBs as it determines the performance as well as the economic viability of the batteries.

fast electronic couplings biomacromoleculesCongratulations to our PhD student Edoardo Cignoni for his publication entitled "A fast method for electronic couplings in embedded multichromophoric systems". Electronic couplings are key to understanding exciton delocalization and transport in natural and artificial light harvesting processes. The authors develop a method to compute couplings in multichromophoric aggregates embedded in complex environments without running expensive quantum chemical calculations. They use a transition charge approximation to represent the quantum mechanical transition densities of the chromophores and an atomistic and polarizable classical model to describe the environment atoms.

sistemi biologici ambienti poco illuminatiStudio computazionale dei complessi LH2 dei batteri fotosintetici per spiegare l’adattamento delle forme di vita agli ambienti scarsamente illuminati.
Quinto appuntamento con il progetto DSCM di comunicazione della scienza nato dalla collaborazione con Microbiologia Italia. L’articolo divulgativo del mese di maggio è stato realizzato dal Dott. Felipe Cardoso Ramos e curato dal Dott. Nicola Di Fidio. “Il processo di fotosintesi, in piante, alghe o batteri, inizia con l’assorbimento della luce solare da parte dei complessi proteici di raccolta della luce (LH) contenenti diversi cromofori. Quest’ultimi sono molecole o sistemi di legami chimici in grado di assorbire radiazioni elettromagnetiche nel campo del visibile e dell’ultravioletto.

reactivity toward co2In this work we computationally investigate the reaction of carbon dioxide with [LAuX] (L =phosphine, N-heterocyclic carbene (NHC); X = Al(NON), B(o-tol)2) complexes to get insights into the Al/B anionic and gold ancillary ligand effects on the Au-Al/B bond nature, electronic structure, and reactivity of these compounds. The Au−Al and Au−B bonds have both an electron-sharing nature, with the diarylboryl gold complexes displaying a more polarized Auδ+−Bδ− bond. The gold ligand (phosphine or N-heterocyclic carbene) has a negligible electronic effect on the Au−X bond, consistently with a radical-like reactivity of the complexes with carbon dioxide, which favors the gold-aluminyl over the gold-diarylboryl complexes.

ppoCongratulations to our Ph.D. student Cosimo Micheletti and to our grant holder Francesco Ventura for their scientific publication entitled “Nanoporous-crystalline and amorphous films of PPO including off-on vapochromic fluorescent 7-hydroxy coumarin guests” in Polymer journal. The study examines the preparation of nanoporous-crystalline and amorphous films of poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) containing 7-hydroxy coumarin (i.e., umbelliferone) for the detection of chloroform vapours.
