Offer Description
Although Iridium complexes have proven to be good and stable candidates to form supramolecular luminescent architectures including coordination polymers,1 their applications are limited due to their high cost and low natural abundance. Hence, over the last decades, as earth-abundant metal complexes, luminescent Cu(I) complexes have received a renewed interest due to economic and environmental concerns. While the use of bulky N^N diimine ligands and P^P diphosphine chelates has been shown to minimise distortion of the excited state of discrete mononuclear copper(I) complexes, thus improving their emission properties, combination of copper(I)-iodide polynuclear entities with organic ligands has also proven successful to afford luminescent complexes. Interestingly, emission of circularly polarised light shows promising applications in (bio)sensors or optoelectronic devices making circularly polarised luminescence (CPL) one of the most attractive chiroptical spectroscopies available. Although, some photoactive Cu(I) complexes showing CPL activity have recently been described, developing new efficient CPL-active chiral Cu(I) emitters remains a challenge.
This projectaims at synthesising new emitting (metallo)ligands and assembling them into luminescent supramolecular covalent cages. A positive impact of the supramolecular architectures on the photophysical properties of Cu(I) complexes is foreseen by rigidification of the overall assembly affording improved Cu(I) emitters. Furthermore, employing chiral ligands will enable formation of new enantiopure Cu(I) complexes as well as chiral covalent cages showing CPL activity. The project builds on recent unpublished preliminary results and one on-going PhD work.

Where to apply
Requirements
Specific Requirements
We are looking for a motivated and dedicated PhD researcher for this project that deals with organic synthesis, supramolecular chemistry, ligand design and (chir)optical properties. The candidate will perform the multi-step synthesis and full characterisation of ligands as well as of new copper complexes and supramolecular cages using standard techniques and spectroscopies (1D/2D NMR, MS, XRD). He/She will also study the optical properties of all compounds (UV-Vis, Em, ECD) and their stability in solution.
The applicant should hold a master degree in molecular chemistry with experience in organic and coordination chemistry. Experience in luminescence measurements will be appreciated but is not mandatory. The candidate should demonstrate the ability to work in cooperative environments as well as autonomously. Communication and personal skills will also be evaluated (fluent English is required).
