Internship in Synthesis and characterizations of Cr(III) organometallic complexes.

University of Brest
Flexible
35 hours a week
C1

​​​​​The quest for earth-abundant phosphorescent emitters has renewed interest for Cr(III) coordination chemistry. The long emission lifetimes of the spin-forbidden transitions of Cr(III) complexes in the near-infrared region appear valuable in diverse applications such as in optical devices, catalysis or even bioimaging. The first generation of compounds is essentially based on classical polypyridyl ligands such as bipyridine, phenanthroline and terpyridine derivatives. However, the photophysical performances of these families of Cr(III) complexes is overall low. Our interests are thus to gain understanding in Cr(III)-based systems and optimize their properties for meeting the requirements for technology transfer.

Tasks and duties entrusted to the student:
  • Synthesis of chromium complexes
  • Chemical caracterizations
  • Optical characterizations (if enough time)
  • Reporting Synthesis and data in a labnote
Skills to be acquired or developed:

This practical training offers an overview on chromium coordination and organometallic chemistry. The internship will mainly focus on synthesis and characterizations of the target complexes. Students will gain experience in laboratory with the use of schlenck line and glove box as well as routine spectroscopic characterizations (NMR, IR, UV-visible). Students will be entrusted with daily lab reports, data analyses and interpretations. The internship will also be the opportunity for students to gain soft skills as organization and communication skills (report and presentation), problem-solving, critical thinking and so on.

Compensation:

Erasmus + grant available depending on eligibility criteria of your home university
