M3 research in the news: Uranium (IV) magnetism

Rodolphe Clérac’s research has been recently cited by the CNRS Institute of Chemistry.  

L’origine du magnétisme atypique de l’ion actinide Uranium(IV) enfin comprise

Les ions de terres rares et d’actinides, qui présentent des propriétés magnétiques remarquables étant données leurs structures électroniques, sont de bons candidats pour entrer dans la composition des aimants de nouvelle génération. Mais alors pourquoi, de manière atypique, l’uranium au degré oxydation IV n’est que faiblement magnétique, alors qu’au regard de sa structure électronique, ses propriétés devraient être comparables aux autres analogues de terres rares ou d’actinides?

M3 research has been recently highlighted by the CNRS Institute of Chemistry

This work demonstrates the possibility of modulating the spin state of the FeII sites and subsequently the magnetic properties of a [2×2] FeII grid-like complex by variation of the degree of deprotonation of the hydrazine-based N-H sites of the ligand in the complex. Evidence has been provided, both in the solid state and in solution, towards understanding the strong influence of the spin-crossover process on the pKas of the grid ligands, which exhibit a unique deprotonation pattern. The present study provides a demonstration of the effect of spin state switching of a chemical property, here on ligand pKa in a metallosupramolecular grid.

M3 research on MEMS cited by the CNRS Institute of Chemistry

Incorporating functional molecules into sensor devices is an emerging area in molecular electronics that aims at exploiting the sensitivity of different molecules to their environment and turning it into an electrical signal. Among the emergent and integrated sensors, microelectromechanical systems (MEMS) are promising for their extreme sensitivity to mechanical events. However, to bring new functions to these devices, the functionalization of their surface with molecules is required. Herein, we present original electronic devices made of an organic microelectromechanical resonator functionalized with switchable magnetic molecules. The change of their mechanical properties and geometry induced by the switching of their magnetic state at a molecular level alters the device’s dynamical behavior, resulting in a change of the resonance frequency. We demonstrate that these devices can be operated to sense light or thermal excitation. Moreover, thanks to the collective interaction of the switchable molecules, the device behaves as a non-volatile memory. Our results open up broad prospects of new flexible photo- and thermo-active hybrid devices for molecule-based data storage and sensors.

Stephanie Beach (Boston University – Doerrer’s group) won a Chateaubriand Fellowship to join our group

Stephanie Beach (Boston University - Doerrer's group) won a Chateaubriand Fellowship to join our group

Stephanie Beach, of the Doerrer Group (Boston University), recently won a prestigious Chateaubriand Fellowship. The Chateaubriand Fellowship is a grant offered by the Embassy of France in the United States. It supports outstanding Ph.D. students from American universities who wish to conduct research in France for a period ranging from 4 to 9 months. Chateaubriand fellows are selected through a merit-based competition, through a collaborative process involving expert evaluators in both countries.

The program is divided into two subprograms: Humanities and Social Sciences (HSS) which supports those who seek to study Humanities and Social Sciences. Stephanie was awarded the Chateaubriand Fellowship in Science, Technology, Engineering, Mathematics & Biology-Health (STEM), which is for doctoral students who aim to initiate or reinforce collaborations, partnerships or joint projects between French and American research teams. This fellowship is offered by the Office for Science & Technology (OST) of the Embassy of France in partnership with American universities and French research organizations such as CNRS, Inserm and Inria.

Stephanie is currently working at the Centre de Recherche Paul Pascal, a CNRS lab, in Bordeaux, France from February through May of 2018 to partner with the group of Prof. Rodolphe Clérac. She is developing new variations of the Doerrer group thiocarboxylate lantern complexes for development as single molecule magnets.

Congratulations Stephanie!

Emergent properties in spin crossover materials

Congratulations to Professor Cameron Kepert (School of Chemistry); Eminent Professor Keith Murray; Dr Suzanne Neville (School of Chemistry) and Dr Rodolphe Clérac on their successful ARC Discovery grant. This project aims to develop ‘intelligent’ materials in which emergent properties arise due to the strategic combination of spin switching with other functionalities. Spin crossover is a versatile form of molecular switch which can reversibly change structure, colour and magnetism using convenient external stimuli. In probing new and interesting forms of interplay between technologically relevant properties, this work addresses the science of host-guest and electronic/magnetic systems and could lead to materials worthy of commercial development to underpin a range of future high-level technologies spanning low energy separations, molecular sensing, data storage, and electronic/magnetic/optical device componentry. Total funding: $612,500
