Bousseksou began his career at the
CNRS Coordination Chemistry Laboratory in
Toulouse as a research fellow in 1993.[1][2] In January 2003, while in charge of Research at the LCC-CNRS Toulouse, he created and directed the scientific team "Switchable Molecular Materials".[3] From 2005 and 2009, he also directed the GDR Magnétisme et Commutation Moléculaires[4] and co-coordinated the GDRI France-Japan on multifunctional molecular materials between 2006-2010. Between 2011 and 2013, he was Deputy Director of the LCC-CNRS
Toulouse and has been Director since 2013. Azzedine Bousseksou was a member of the CNRS national committee for the evaluation of researchers and research laboratories from 2000 to 2004 and 2010 to 2015 and has coordinated and/or led several European, national, and regional projects. He has been a member of the European Network of Excellence on Molecular Magnetism, REX MAGMANET,[5] and is a member of the
European Institute on Molecular Magnetism (EIMM).
He and his team developed three complementary conceptual approaches, which include:
The transition from spin & Nano-Electronic Transport (molecular
spintronics) with the setting up of the very first molecular devices allowing the coupling of a spin state with electronic transport in a nanometric junction,
The transition from spin & optics towards high-performance
photonic devices with the implementation of Nano-Thermometric Sensors (patented) that surpass current commercial devices,
Spin transition & reversible variation of molecular volume with the realization of the first Nano-Actuators with controlled direction whose chemical combination with polymers allowed the implementation of active materials "artificial muscles" with advanced applications in
robotics and Micro-Nano-Mechanics.
With his research team made up of 3 other permanent staff members (Gabor Molnar, DR-CNRS, Lionel Salmon DR-CNRS and William Nicolazzi, MCF-Université Paul Sabatier), among his most remarkable achievements are the following:
The development of the lsing-type model with two electronic levels for one- and two-step spin transition with prediction of symmetry breaks.[6]
The discovery of the first magneto-switching by the application of an intense magnetic field (32 Tesla) pulsed into the hysteresis cycle of a spin transition molecule (Fe(Phen)2(NCS)2) allowing the information to be addressed from the high spin (HS) state to the low spin (BS) state, by a nucleation growth phenomenon whose dynamic effects are the subject of particular attention at the experimental and theoretical levels.[7][8]
The discovery of the first hysteresis of the dielectric constant in spin-transition complexes.[9][10][11]
The discovery of the first double photo-switching in binuclear spin-transition compounds[12]
The first photo-switching at room temperature.[13]
The first synthesis of spin-transition thin films at room temperature (new layer-by-layer concept for spin transition).[11][14]
The first Nano-Structuring of Bistable materials with spin transition at room temperature.[15]
The synthesis of the smallest spin-transition coordination nanoparticles (4 nm) with hysteresis around room temperature.[16]
The original synthesis of a hybrid system combining spin transition and fluorescence for the purpose of detecting the spin transition property on the single Nano-Object.[17]
The development of a new generation of active devices based on photonic/plasmonic spin-transition materials,[18] diffractive gas sensors,[19] Nano-Thermometers[17] and also Nano-Electronics,[20] and spintronic devices.[21]
The recent development of switchable molecular materials for direction-controlled micro- and Nano-Actuation by exploiting the reversible volume variation of spin-transition molecules (development of the first artificial muscle prototypes) with thermo- or photo-induced actuation for robotic applications (ERC 2019 project under evaluation).[22][23][24][25][26]
He has supervised about twenty post-doctoral students and more than thirty theses.
He has registered 12 patents, 2 of which are being exploited, and one startup in incubation.
