Offer Description
The LIGHTinPARIS programme has launched its 3rd call for PhD Fellowships with up to 6 fully funded positions starting on 1 January 2027. The PhD projects on offer fall in the domain of the Institute for Sciences of Light (Université Paris-Saclay) covering photonics, optics, imaging, materials (chemistry), lasers, instrumentation, information, quantum technologies and more. The programme is cofunded by the European Union under Horizon Europe Marie Skłodowska-Curie Actions (MSCA) COFUND call and co-financed by Université Paris-Saclay and two non-academic partners IMAGINE OPTIC and ONERA.
This is an announcement for one of the 10 PhD projects on offer.
CHISOS: CHIral Saddle-shaped Organic Semiconductors
Optical rotation, electronic circular dichroism (ECD), and circularly polarized luminescence (CPL) techniques clearly confirm the ability of optically active molecules to modulate the properties of circularly polarized light. This specific interaction between light and chiral matter has generated considerable interest within the scientific community due to its practical applications in various fields and is now considered a cutting-edge technology for 3D display devices. With this in mind, we will explore the synthesis and photophysical and chiroptical properties of enantioenriched chromophores based on combinations of COTPh or COTTh and porphyrin pigments, thereby creating new families of 3D OSCs with improved solubility, stability, and chiroptical activities, thanks to the synergy between the saddle-shaped core and the pigment properties.
Keywords: Organic semiconductor; Chirality; Cyclooctatetraphenylene; Chiroptical activities / Multifunctional materials; CP-OLEDs devices
PI/Thesis Supervisor and team: David KREHER (and Kaïs Dhbaibi) at the SORG team (axe matériaux moléculaires) at the ILV laboratory / institute of UVSQ
Every LIGHTinPARIS PhD project includes a “3i” dimension (interdisciplinary, intersectoral, or international collaboration) and all fellows will benefit from secondment opportunities for 2 to 12 months at the 3i partner lab under the supervision of the “3i” co-supervisor.
3i dimension(s) for project CHISOS: interdisciplinary at CEA Paris-Saclay/IRAMIS/SPEC/GMT group and international (short stays at the OPERA Lab, Kyushu University - Japan)
