This post-doctoral research work aims at investigating trianguleniums as an original class of robust organic dyes to challenge rare metal based photosensitizers for the catalytic reduction of protons (H2 production) and CO2 using visible light. Coupled to a sacrificial electron donor and a molecular catalyst, these dyes will give access to efficient and stable photocatalytic systems only composed of earth-abundant elements. Such fundamental achievements will have a direct impact on the development of artificial photosynthetic systems still greatly limited by the use of rare metal based photosensitizers.


The candidate will be in charge of studying the redox (by molecular electrochemistry), photophysical (by stationary and time-resolved absorption and emission spectroscopies) and photocatalytic (light irradiation in the presence of a catalyst and an electron donor, followed by gas chromatography coupled to mass spectrometry) properties of these new dyes. These studies will be carried out at the “Département de Chimie Moléculaire” (DCM) at the “Université Grenoble Alpes”. The multi-step synthesis of these new triangulenium dyes as well as their characterization (NMR, mass spectrometry, X structure,...) will be carried out by another post-doctoral fellow at the ITODYS laboratory at the “Université de Paris”.


The candidate must be an experienced chemist in photocatalysis. Experience in molecular electrochemistry or photochemistry may be an asset (but not mandatory). The candidate will be rigorous, creative, highly motivated and hard-worker. He/she should be able to work in a team environment but also work independently with a minimum of supervision. The candidate will be fluent in French or English. Please provide a curriculum vitae, a cover letter and the contact details of at least two referees.

Work Context

This research work is funded by the French National Research Agency (ANR) under the acronym TATADyes and will be carried out in the framework of a collaboration between the “Département de Chimie Moléculaire” (UMR 5250) at the “Université Grenoble Alpes” within the group of “Chimie Inorganique Rédox” (CIRE, Dr Jérôme Fortage) and the ITODYS laboratory (UMR 7086) at the “Université de Paris” within the group of “Transduction Moléculaire et Supramoléculaire” (TMS, Dr Philippe Lainé). This project is built on the recent work of these two teams with a triazatriangulenium dye for visible-light H2 production in water which highlights for the first time the great potential of this family of organic dyes in photo-induced electron transfer reactions to drive catalytic processes (ACS catal. 2018, 8, 3792-3802).

The “Département de Chimie Moléculaire” (DCM) is a joint CNRS/Université Grenoble Alpes unit (UMR 5250) mobilizing nearly 80 permanent researchers/teachers/ITA/IATOSS and as many doctoral students, post-doctoral students and masters, around two interactive research axes, namely chemistry for health and chemistry for nanoscience. In addition, the DCM is structured in 5 research teams, each with a scientific theme, with in particular the CIRE team (Chimie Inorganique Rédox) which has strong competences in molecular electrochemistry and redox photochemistry. Being the largest team of the DCM with 27 permanent staffs, the CIRE team is subdivided into 4 subgroups, including the group "Artificial Photosynthesis and Energy Carrier" (PhotoArt) which displays a strong expertise in the field of photo- and electrocatalysis devoted to the reduction of CO2 and protons to H2, and more broadly to the dissociation of water into O2 and H2, as well as in the electrochemical and photophysical characterization of photo- and electro-induced catalytic processes. The PhotoArt group has all the electrochemical and photophysical instruments necessary to carry out this work. The successful candidate will work in the PhotoArt group under the supervision of Dr. Jérôme Fortage (CRCN CNRS).

Constraints and risks

The candidate will be required to handle aqueous or organic solutions containing low toxicity chemicals. He/she will regularly use lasers (class 4) for photophysical studies and powerful Xe irradiation lamps (light intensity of about 100 mW/cm²) for photocatalysis.
