Updating NMR Equipments at the SeRMN – UAB

To improve the obsolescence of current equipments, the following new NMR spectrometers will be installed at the SeRMN-UAB Facility in May 2021:

  1. A new AVANCE NEO console for the existing 500 MHz NMR spectrometer, equipped with an automated ATMA accessory and a compatible cryoplatform for the current TCI cryoprobe.
  2. A New 400 MHz NMR spectrometer including a ultrashielded ASCEND magnet, automated SAMPLE-CASE sample changer, high-resolution liquid (iProbe) and solid-state (CP-MAS 4.0mm) NMR probes, and a BCU-II unit for automated sample refrigeration until 233K.
  3. A New 300 MHz NMR spectrometer including a Nanobay AVANCE NEO console, ultrashielded ASCEND magnet and a BBFO probehead, and a BCU-II unit for automated sample refrigeration until 233K.
  4. A cooled SAMPLE-CASE sample changer for the existing 600MHz NMR spectrometer.

More info about the equipments and accesories can be found at the Bruker WWW site.

22-06-2020: Updating Operation Mode in the SeRMN – UAB

From 22-6-2020, all authorized SeRMN users can make use of the self-service mode in the 250auto, 360MHz and 400MHz spectrometers, exclusively from 9AM to 5PM, using the booking program ( The experiment request service is also active for all those samples that are not recorded in self-service mode:

    Solution NMR form:
    Solid State NMR:
MRI/MRS studies (Biospec) :
    Another Request :

At the moment, the 250robot spectrometer is reserved exclusively for this type of work.

It is very important that the following mandatory rules are respectedt
1. Self-service exclusively from 9AM to 5PM. SeRMN access is not allowed outside of this time slot as there will be no SeRMN staff.
2. Only 1 person per machine is allowed. Always respect two meters of distance separation between people.
3. It is necessary to follow the established protocols of hygiene and safety at a personal level (mask, hand disinfection …)
4. Before and, above all, after using the keyboard and other tools to carry out the experiments (spinner, calibrator …) it is necessary to disinfect them with the hygiene material that you will find available.

Any questions or clarifications, you can contact the staff of the SeRMN who will be present from 9AM to 5PM or through the address .

COVID-19: Reobrim el SeRMN-UAB el dilluns 25 de Maig /Reopening the NMR Service from Monday 25th May

Després de més de dos mesos d’obligat tancament, el SeRMN reobrirà les seves instal.lacions a partir del proper dilluns dia 25 de Maig. Ja que s’han de mantenir certes precaucions de seguretat i higiene, començarem amb un funcionament limitat, provisional i progressiu a mida que es vagi normalitzant la situació del COVID19. Les normes bàsiques de funcionament són:

1. No hi ha autoservei. No cal fer reserva en el nostre sistema de reserves com es fa habitualment. Les mostres seran analitzades exclusivament pel personal del SeRMN.

2. Prèviament, cal fer una sol.licitud de prestació de servei per a cada mostra a través dels formularis de la nostra plana web:

    Sol.licitud RMN en solució :
    RMN en estat sòlid :
    Estudis MRI/MRS (Biospec) :
Altra Sol.licitud :

3. Pels usuaris que treballin a l’edifici de les Facultats de Ciències i Biociències, cal portar la mostra presencialment al SeRMN en horari de matí (9AM-1PM). És important que la mostra estigui ben etiquetada i prèviament desinfectada. L’accés al SeRMN està restringit. Just a l’entrada del SeRMN hi haurà una taula de recepció per desinfectar/deixar/recuperar les mostres (veure

4. Degut a l’accés restringit que hi ha a l’edifici de les Facultats de Ciències i Biociències, recomanen als usuaris externs sense autorització d’accés a l’edifici (altres facultats de la UAB, instituts i empreses del PRUAB, i instituts i empreses externes al PRUAB) que es posin en contacte amb el personal del SeRMN per email o per telèfon (93 581 3785 o al 93 581 2291) per concretar el lliurament/recollida de mostres.

Per qualsevol dubte o qüestió, podeu contactar-nos a través del nostre mail institucional () o en els nostres correus personals.


After more than two months of forced closure, the SeRMN will reopen its facilities from next Monday, May 25. Since certain safety and hygiene precautions must be maintained, we will start with a limited, provisional and progressive operation as the COVID-19 situation normalizes. The basic rules of operation are:

1-. There is no self-service. There is no need to make a reservation in our booking system as usual. Samples will be analyzed exclusively by the SeRMN staff.

2-. Previously, a request for service for each sample through the forms on our website is required:

    Solution NMR form:
    Solid State NMR:
MRI/MRS studies (Biospec) :
    Another Request :

3.- For users working in the building of the Faculties of Sciences and Biosciences, the sample must be brought in person at the SeRMN in the morning (9 AM-1PM). It is important that the sample is well labeled and previously disinfected. The access to the SeRMN lab is restricted. Right at the entrance of the SeRMN there will be a reception table where you must disinfect / leave / recover your samples (see

4. Due to the restricted access to the building of the Faculties of Sciences and Biosciences, we strongly recommend to external users without authorization access to the building (other faculties of the UAB, institutes and companies of the PRUAB, and institutes and companies external to the PRUAB) that contact with the staff of the SeRMN by email or telephone (93 581 3785 or 93 581 2291) to specify the delivery of samples.

For any questions or concerns, you can contact us via our institutional email () or in our personal emails.

A new strategy for the regioselective functionalization of C60 fullerenes

Supramolecular Fullerene Sponges as Catalytic Masks for Regioselective Functionalization of C60“, by Carles Fuertes-Espinosa, Cristina García-Simón, Míriam Pujals, Marc Garcia-Borràs, Laura Gómez, Teodor Parella, Judit Juanhuix, Inhar Imaz, Daniel Maspoch, Miquel Costas and Xavi Ribas.

Chem, in press (2020). DOI: 10.1016/j.chempr.2019.10.010

The supramolecular mask protocol is a significant step forward for the regioselective functionalization of fullerenes. The exquisite ability to form pure-isomer poly-functionalized C60 adducts, overcoming tedious and non-practical chromatographic separations, allows for their direct testing in solar cell prototypes. Furthermore, the supramolecular mask strategy can be applied to C70 or higher fullerenes, opening a plethora of poly-functionalized fullerene derivatives to be synthesized and tested. Moreover, apart from the nucleophilic cyclopropanations reported herein, the protocol is currently being expanded to Diels-Alder (DA), 1,3-dipolar cycloadditions and PC60BM-type cyclopropanations, thus enabling a variety of regioselective functionalization reactions. This supramolecular mask strategy can help the discovery of the next generation of improved solar cells (organic or perovskite based) or new drug candidates.

This research has been carried out in close collaboration with Dr. Xavi Ribas (from the QBIS-CAT research group of the University of Girona (UdG)), the Catalan Institute of Nanotechnology (ICN2), the ALBA-BCN synchrotron and the NMR Service of the Autonomous University of Barcelona ( UAB). The results have just been published in the online version of the prestigious CHEM scientific journal .

Two complementary 1D NMR approaches for the fast and easy determination of the magnitude and the sign of heteronuclear J(XH) coupling constants are proposed:The Up&Down technique relies on the direct analysis of anti-phase multiplets whereas the Left&Right technique is based on the relative displacement between separate IPAP components.
