Missions

The recruited researcher will work in the frame of PHOTOMIC (Photochromic Organic Materials for Neuromorphic Computing) project. The main part of the project will be the synthesis of organic photochromic molecules, more precisely diarylethenes, sensitive in the near infrared. The final target is to integrate them in synapses of artificial optical neuronic networks.

Activities

Main tasks:
• Synthesis and charaterization (NMR) of organic photochromic molecules
• Measurement and analysis of photochromic properties (composition under irradiation, photokinetics)
Self-sufficiency in these tasks are expected.

Skills

The postdoctoral researcher must be a PhD holder in organic synthesis.
Experience in the synthesis of photochromic organic molecules, as well as in the study of photophysical and photochemical properties of photoactive molecules are welcomed. Abilities in team work and in interpersonal communication are required for a fluid progress of the project.

Work Context

PHOTOMIC project is supported by the ANR (Agence National de la Recherche), a major French funding agency. The researcher will be recruited at the "Laboratoire de Photophysique et de Photochimie Supramoléculaires et Macromoléculaires" (PPSM, ENS Paris-Saclay, CNRS), whose role is, among others, to synthesize photochromic molecules. PHOTOMIC project also involves two other laboratories, located in the Paris-Saclay scientific cluster: "Service de Physique de l'État Condensé" (SPEC, CEA-Saclay, Orme des Merisiers Site) and "Centre de Nanosciences et de Nanotechnologies" (C2N, Université Paris-Saclay, CNRS).
This project's ambition is to assess photochromic materials for neuromorphic computing, by an organic photonic approach.

Constraints and risks

The researcher will need to manipulate chemicals and optical instruments (including lasers).
