The comeback of the Labtour[2024]

Posted on by
  • Context : In line with our previous initiatives during autumn 2022/winter 2023,  we are continuing to strengthen community interaction within KiNOA by organizing laboratory visits.
  • Deadline for enlisting the visits : 15/03/2024
  • Where ? on the framalink sent the 28/02
  • Remind : The concept is to welcome colleagues to your lab (or experiment) at a time and duration that suits your schedule.
  • Encourage you to share this information with all members of your group. It presents a valuable opportunity for them to broaden their understanding of chirality.

Bulk electrosynthesis of patchy particles with highly controlled asymmetric features

Posted on by
2024-01-16
News: Asymmetric modification of particles with various patches of different composition and size at predefined positions is an important challenge in contemporary surface chemistry, as such particles have numerous potential applications, ranging from materials science and (photo)catalysis to self-assembly and drug delivery. However, approaches allowing the synthesis of this kind of complex objects in the bulk of a solution in a straightforward way are currently lacking. In this context, bipolar electrochemistry (BE) is a powerful technique for the asymmetric modification of conducting objects. Herein, this approach is used for the highly controlled modification of particles with different metal patches, generated at specific locations of isotropic objects. The synthesis is carried out in the bulk of the solution and leads to predefined patterns of increasing complexity, including even a specific chiral arrangement of the patches.

Modulation of circularly polarized luminescence by swelling of microgels functionalized with enantiopure [Ru(bpy)3]2+ luminophores

Posted on by
2023-12-20
News: Chemoresponsive microgels functionalized with enantiomeric D- or K-[Ru(bpy)3] 2+ showed tunable chiroptical properties upon swelling and shrinking. The tuning is triggered by a modulation of the local mobility of [Ru(bpy)3]2+ upon addition of fructose, controlling inter- actions and distances between [Ru(bpy)3]2+ and phenylboronic acid.

Design, preparation and chiroptical characterization of chiral molecules and monolayers for Chirality Induced Spin Selectivity studies

Posted on by
Supervisor : mathieu.gonidec@icmcb.cnrs.fr
Laboratory/campus : ICMCB
Starting date : 2023-09-15
Duration/month : 36
Preferred Majors for applicants : chemistry
The main goal of this project is to provide systematic comparative studies to rationalize the occurrence and magnitude of the CISS effect in molecular nanodevices. In order to reach those objectives, we will synthesize series of coordination compounds designed to present a range of stable chiroptical activities, that will be deposited as thin films or grafted as monolayers on metallic substrates while preserving both their structure and their enantiopurity. We will then thoroughly study the chiroptical properties of these thin films by a range of surface sensitive spectroscopies. Ultimately, the CISS effect induced by these chiral surfaces will be studied (partly in house, partly with the help of external collaborators) by integrating them into vertical charge transport devices to probe their spin dependent properties and analyze their CISS activity.
