Logo

The Quantum Chemistry Group of the Universitat Rovira i Virgili (URV) has a quite long tradition, its research activity having started at the end of the 1970s. The primary goal of the QGC is to contribute to the understanding of the electronic structure and the derived properties of a large variety of systems, related by a common aspect: their complexity. The present research lines involve the analysis and modeling of catalytic reaction mechanisms, both homogeneous and heterogeneous, the study of photochemical reactions, the interpretation of spectroscopic phenomena, of red-ox properties or the magnetic behaviour of a variety of materials, from molecules, to clusters and solids. Professor Josep M. Poblet is the current director of the group. Former directors have been Professor Enric Canadell (1979-1983) and Professor Rosa Caballol (1983-2008).

The Quantum Chemistry Group belongs to the Department of Physical and Inorganic Chemistry and develops all its activities at the Faculty of Chemistry. The group also belongs to the Reference Net in Theoretical and Computational Chemistry (Xarxa de Referència d'R+D+I de Química Teòrica i Computacional).

Recently, the QCG has been audited and received the ISO 9001 certificate, which is granted by the German organization TÜV Rheinland.

C60_blue-emission DOI: 10.19061/iochem-bd-2-84

The unusual UV/blue-green fluorescence of [60]fullerene at micromolar concentrations in ethyl acetate has been investigated using steady-state and time-resolved fluorescence techniques. This broad emission exhibits longer lifetimes than the well-known red fluorescence typically associated with C60. The relative intensity of the blue and red emission bands is influenced by several factors, including sonication, solvent polarity, the presence of additives (e.g., inert gases or oxygen), and excitation wavelength. Evidence from time-resolved fluorescence anisotropy and computational studies suggests that this emission originates from the formation of ~2 nm-sized fluorophores due to weak intermolecular π–π van der Waals interactions, which become ineffective at concentrations between 2–4 μM. Analysis of the blue/red emission behavior has enabled the estimation of C60 solubility in ethyl acetate at approximately 2 μM.

PV14-benzylammonium_in_water DOI: 10.19061/iochem-bd-2-61

The new benzylammonium (C7H10N) salt of the phosphotetradecavanadate (PV14) anion PV14O429-, (C7H10N)(6)[H3PV14O42]center dot 7H(2)O (1), is synthesized under mild conditions and characterized by a combination of physicochemical techniques such as Fourier transform infrared spectroscopy, powder X-ray diffraction, elemental analyses and cyclic voltammetry. As evaluated by V-51 NMR spectroscopy, at milimolar concentrations and pH similar to 2.5 the PV14 anions decompose slowly, thus demonstrating kinetic stability, but at pH similar to 7 this process takes place much faster. However, in the presence of human serum albumin, the V-51 NMR peaks of PV14 anions broaden significantly and their decomposition becomes much slower, this being due to a direct interaction between both components. The structure of 1 is elucidated by single-crystal X-ray diffraction and reveals the presence of three-fold protonated, bicapped Keggin type [H3PV14O42](6-) anions. The supramolecular interactions governing the crystal packing are further studied using the Hirshfeld surface analysis. Computational studies using density functional theory were effective in determining the electronic and protonation states of PV14 clusters, as well as the multi-electron redox behavior of compound 1 in acidic aqueous solutions. Molecular dynamics calculations confirm the high hydrophilicity and absence of aggregation between protonated PV14 anions in aqueous medium. Notably, this compound shows high inhibitory effect on the viability of the U87 glioblastoma cell line with IC50 values of 3.2 +/- 0.6 mu M and 1.10 +/- 0.04 mu M after 24 h and 72 h treatments. The mode of action of compound 1 is mediated by the pro-apoptotic process. These data provide evidence on the potential therapeutic use of PV14 compounds against glioblastoma.

Unusual_C2h-symmetric_trans-1-(bis-pyrrolidine)-tetra-malonate_h DOI: 10.19061/iochem-bd-2-18

A totally unanticipated regio- and stereoisomerically pure C2h-symmetric trans-1-(bis-pyrrolidine)-tetra-malonate hexa-adduct of C60 was obtained via a topologically controlled method, followed by a 1,3-dipolar cycloaddition reaction. The structures of the products were elucidated by 1H and 13C NMR and by X-ray crystallography. The unexpected regio- and stereoselectivity observed, supported by theoretical calculations, was found to be a consequence of malonate–pyrrolidine interactions.

V10 Bioactivity DOI: 10.19061/iochem-bd-2-82

This project investigates the proton-coupled electron transfer (PCET) behavior of vanadium oxide clusters: V₁, V₂, V₄, and V₁₀. Using DFT, calculations were performed both on the isolated vanadate species and in the presence of organic cations H·4-Me₂AmPy⁺ and H·1-MeIm⁺. The aim is to understand how these cations affect the redox properties and PCET thermodynamics of the clusters. The dataset includes optimized geometries, electronic energies, and free energy profiles that map both stepwise and concerted PCET pathways, providing insights into how ion pairing may influence electron and proton dynamics.
