Well-defined fullerene-PEG conjugates, C60-PEG (1) and two C70-PEG (2 and 3 with the addition sites on ab-[6,6] and cc-[6,6]-junctions), were prepared from their corresponding Prato monoadduct precursors. The resulting highly water-soluble fullerene-PEG conjugates 1–3 were evaluated for their DNA-cleaving activities and reactive oxygen species (ROS) generation under visible light irradiation. Unexpectedly, photoinduced cleavage of DNA by C60-PEG 1 was much higher than that by

The journal Journal of Materials Chemistry C features on its front cover the recently published paper “Photoinduced electron transfer in mechanically interlocked suit[3]ane systems”. Suitanes, a new class of two-component mechanically interlocked systems, have recently been developed. In this work, we report a detailed study of photoinduced electron-transfer processes in suit[3]anes consisting of a 3-fold
This month took place the Summer edition of the IQCC Forum, a quarterly meeting-place where high-quality science is discussed. The IQCC Forum gives the opportunity for PhD and postdoc members of the IQCC to present their work to a select group of critical researchers, enhancing intra-IQCC collaborations and promoting knowledge exchange within the institute. This
This week, our former member of IQCC Carles Fuertes was awarded the annual recognition of the best PhD thesis in 2020 (Premi Extraordinari) from the University of Girona. Last year, he defended with success his PhD thesis on “Supramolecular nanocapsules as platforms for molecular recognition and reactivity in confined spaces”, supervised by Xavi Ribas. Now,
This week at the Supr@Stras conference organized by European Journal of Organic Chemistry, Chemistry Europe and Supramolecular Chemistry Group from SCF included a virtual poster session on Twitter (27th July). Ernest Ubasart, PhD student under the supervision of Dr. Xavi Ribas, presented a poster titled “A new supramolecular nanocapsule that enables the bis-regiofunctionalization of C60 and
Last week at the 2021 online edition of the International Symposium on Macrocyclic and Supramolecular Chemistry (ISMSC2021), Ricard López-Coll, PhD student under the supervision of Dr. Agustí Lledó, presented a poster titled “Exploring the Fluxional Behavior of Bioinspired Artifical Receptors with (a)MD Simulations”, and won the poster prize! The poster described the collaborative study between the groups
Dr. Sergio Posada-Pérez has recently become a new member of the Institute of Computational Chemistry and Catalysis (IQCC) with Juan de la Cierva – Formación and Marie Sklodowska-Curie IF fellowships, Dr. Posada-Pérez did his PhD at the University of Barcelona on heterogeneous catalysis of green chemistry reactions on molybdenum carbide based catalysts under the supervision of
This paper on melanin components is the first one coming from the MSCA-IF of Jun Wang with Lluís Blancafort. Melanin is the photoprotecting material in living organisms, and it is composed of dihydroxyindole oligomers. We have studied a comprehensive virtual library of minimal oligomer models and obtained insights into the stability and optical properties that
The journal European Journal of Inorganic Chemistry features on its front cover the recently published minireview “Fundamental Basis for Implementing Oxidant-Free Au(I)/Au(III) Catalysis”. Oxidant-free Au(I)/Au(III) catalysis can still be regarded as a young and promising chemistry. Because the first examples of gold catalysis were limited to the activation and functionalization of ?-C?C bonds and very little was
Unspecific peroxygenases (UPOs) enable oxyfunctionalizations of a broad substrate range with unparalleled activities. Tailoring these enzymes for chemo- and regioselective transformations represents a grand challenge due to the difficulties in their heterologous productions and lack of structural data. In a new collaboration by the research teams leaded by Dr. Martin Weissenborn (Leibniz Institute of Plant Biochemistry,
