Missions

Networks of molecularly functionalized nanoparticles (NPs) (hereafter called NMN: nanoparticle molecule network) have emerged as an interesting approach in molecular electronics to understand fundamental electron transport mechanisms, as well as to develop potential applications in electronics, sensing and computing circuits. The long-term objective in the field of electronics and unconventional computing circuits is to use a network of self-assembled metallic nanoparticles connected by electrically switchable molecules to implement reconfigurable logic gates though algorithms.
In this project, we will explore electron transport at high frequency and dynamics in NMNs made of Au NPs functionalized by various types of novel molecular building blocks, tailored to exhibit event-driven evolving functionalities. We will address three classes of molecules: i) optically driven switches; ii) THz activated switches and iii) ion molecular switches.
The main goal of the postdoc work will be to synthesize functionalized π-conjugated systems belonging to the aforementioned three classes of molecules and characterize their physicochemical properties. Then, these molecules exhibiting thiol groups will be used for the preparation of functionalized Au NPs.

Activities

Responsible for the following main activities:
- synthesize functionalized π-conjugated systems belonging to the three above-mentioned classes of molecules and characterize their physicochemical properties
- synthesize and characterize gold nanoparticles functionalized by the new prepared π-conjugated systems
- make regular updates on the progress of the project
- write activity reports
- interact with the project partner (IEMN Lille)

Skills

- Candidates holding a doctorate in organic chemistry and having previous experiences relevant to the mentioned project
- Candidates with experience in the synthesis and characterization of π-conjugated systems (absorption and emission spectroscopies, cyclic voltammetry)
- Additional experience in synthesis and characterization of gold NP would be appreciated
- Due to the interdisciplinary nature of the work, the candidate will have to work in collaboration with the physicist partners of the IEMN
- A very good ability to communicate scientific results in English, both orally and in writing, is required.
- Team working
- Be independent

Work Context

This work will be developed at MOLTECH-Anjou at the University of Angers (France) in the frame of the EVOLMONET (Evolving electronic transport in molecules/nanoparticles networks) project. The latter is funded by the French National Research Agency (ANR) and will be carried out in strong interactions with our partner at IEMN (Institut d'Électronique, de Microélectronique et de Nanotechnologie) in Lille (France).

The MOLTECH-Anjou laboratory is a Joint Research Unit of the CNRS and the University of Angers (UMR 6200) located at the Faculty of Sciences, 2 Bd Lavoisier 49045 ANGERS Cedex, France. It brings together the skills of 80 people, including around fifty CNRS researchers, Professors and Associate Professors, engineers and technical staff, and around thirty doctoral students and post-doctoral researchers.
The scientific activity of the MOLTECH-Anjou laboratory is centered on the development of organic molecular materials or organic-inorganic hybrids, in support of high-visibility axes such as organic electronics, stimulable materials, material nano-structuration or even materials for energy. Five research teams pool their expertise (theoretical chemistry and modeling, organic and inorganic syntheses, coordination chemistry, supramolecular, physical and analytical chemistry, elaboration of materials) and in photonics. Four teams belong to the National Institute of Chemistry of the CNRS (INC), the fifth coming from the National Institute of Physics of the CNRS.
