Purification of Sc-metallofullerenes by a supramolecular nanocapsule

A self-assembled Cu(II)-based nanocapsule enables efficient and straightforward isolation of Sc3N@C80 from arc-processed raw soot. The newly designed Cu(II)-based supramolecular nanocapsule 5·(OTf)8 was used to effectively entrap fullerenes and endohedral metallofullerenes (EMFs) with different affinities depending on their size and shape. Moreover, we took advantage of the sharply different entrapment abilities of the 5·(OTf)8 cage

Photodissociation of Iron(IV)-Oxo Complexes: The evasive Fe=O stretch

We demonstrate the application of infrared photodissocation spectroscopy for determination of the Fe=O stretching frequencies of high-valent iron(IV)-oxo complexes [(L)Fe(O)(X)]2+/+ (L = TMC, N4Py, PyTACN, and X = CH3CN, CF3SO3, ClO4, CF3COO, NO3, N3). We show that the values determined by resonance Raman spectroscopy in acetonitrile solutions are on average 9 cm-1 red-shifted with respect

Activation of Dioxygen at a Lewis Acidic Nickel(II) Complex

In metal-mediated O2 activation, nickel(II) compounds hardly play a role, but recently it has been shown that enzymes can use nickel(II) for O2 activation. Now a low-coordinate Lewis acidic nickel(II) complex has been synthesized that reacts with O2 to give a nickel(II) organoperoxide, as proposed for the enzymatic system. Its formation was studied further by

First two speakers of Girona Seminar 2018

Following today’s Nobel ceremony from Stockholm, it is our honor to announce the first two speakers of the Girona Seminar 2018, which will take place in Girona from April 4-6, 2018. Prof. Larry Que (Minnesota) has been a regular collaborator, mentor and supervisor of several members of the IQCC. He has published ca. 500 papers

Congratulations to all (previous) members of IQCC

At the beginning of August, the Nature Publishing Group sent out a mail titled “Is your institution a Rising Star?” to all people with an user account at NPG. Interestingly enough, at place 84 of the Nature Index 2016 Rising Stars we find the University of Girona (UdG), as only representative of Spain. The Nature

Juan Pablo Martínez, the latest doctor of the IQCC

On 18 november 2016, Juan Pablo Martínez defended with success his PhD Thesis titled “Reactivity of Fullerenes, Endohedral Metallofullerenes, and Nanotubes, and their Possible Application in Solar Energy Conversion” in the Sala de Graus of the Faculty of Science (UdG). The members of the evaluation Committee were Prof. Dr. Frank de Proft from Vrije Universiteit

Excitonic photocatalytic oxidation of methanol

CH3OH on a single-crystal rutile TiO2(110) surface is a widely studied model system for heterogeneous photocatalysis. The oxidation to CH2O is stepwise and involves a CH3O intermediate. These photocatalytic processes are usually modeled assuming that the hole-electron (h-e) pairs generated during the excitation are independent, ie they separate before the reactive photocatalytic step. Here we show

Second edition of Science Slam IQCC, November 24, 12.00h

In 2015, the IQCC organized for the first time the Science Slam, which took place within the general context of the Setmana de la Ciència and was dedicated to Prof. Ramon Carbó-Dorca on the occasion of his 75th birthday. Next week on November 24 the IQCC organizes the second edition to show the most representative

Spinning around in Transition-Metal Chemistry

Spin states of transition-metal complexes are essential for understanding many cases in biology, medicine, catalysis, and photonics. The choice of theoretical method, basis set, solvation and many other effects represent factors that need to be considered to be able to deal with the close-lying spin states in coordination compounds. However, the assignment of spin states
