Conférences MOLTECH Anjou – 15 mai

Dr. Erwan Nicol et Dr. Olivier Colombani de l’IMMM présenteront leurs travaux à travers deux conférences, qui auront lieu dans l’amphithéâtre L003.

  • 11h00-11h30 : Erwan Nicol, “Hydrogels auto-assemblés photo-réticulables à base de poly(éthylène glycol) (PEG) : un potentiel applicatif en biologie
  • 11h30-12h00 : Olivier Colombani, “Homogeneous, Janus and stimuli-responsive supramolecular nanocylinders via hydrogen bonding polymers in solution”

Conférence CEISAM – 15 mai

Ally Aukauloo (Université Paris-Saclay) donnera une conférence le lundi 15 mai à 15h15 salle Marie Curie.

Le sujet de sa conférence portera sur: « Organic semiconductors and molecular complexes for artificial photosysnthesis ».

« Artificial photosynthesis aims to reproduce the catalytic power of enzymes from the capture of sunlight to strip electrons and protons from water to reduce CO2 or uses light to activate O2 to perform oxidation chemistry in a selective way. I will discuss on our recent results in these research thrusts:
i) Organic semiconductors for the water splitting reaction
ii) CO2 to CO transformation with iron porphyrins catalysts

While often trapping intermediates following chemical and electrochemical pathways are tedious, using a photoredox module to interrogate the light driven activation processes can be alternative and elegant route.

MOLTECH Anjou Conference – June 1

Dr. Pascal Kaienburg, EPSRC Postdoctoral Fellow, Clarendon Laboratory, Department of Physics, University of Oxford, donnera une conférence intitulée :
Small-Molecule Organic Photovoltaics – Electronic & Microstructure Properties“.

Date et lieu: jeudi 1er juin à 11h00 dans l’amphi L003


Gloria Cardenas-Jiron, Laboratory of Theoretical Chemistry, Faculty of Chemistry and Biology, UNIVERSITY OF SANTIAGO DE CHILE (USACH), CHILE will give a lecture at the University of Angers


Date and place: Wednesday March 22 at 11:00 a.m. in auditorium L004


“Expanded porphyrins are macrocycles containing more than four pyrrole rings with an enhancement of the p-electron conjugation. Because of the larger number of pyrrole rings compared with porphyrins, they have attracted great interest in dye-sensitized solar cells (DSSC).

Photophysical, photovoltaics, and charge transport properties of porphyrin and expanded porphyrins are inspected using density functional theory (DFT), time-dependent DFT, and a combination of the Keldysh nonequilibrium Green′s function formalism with the DFT (DFT-NEGF). Several strategies in the molecular structure are assessed, and their effects on these properties are investigated.

EUR LUMOMAT launches its first SUMMER SCHOOL “Sustainable strategies for Organic Electronics” which will take place in Angers from June 26 to 30, 2023.

“The field of organic electronics continues to advance at a rapid pace towards the next generation of electronics. This development requires new organic materials to act as semiconductors, in particular for the fabrication of organic field effect transistors (OFETs), organic light emitting diodes (OLEDs) thermoelectric devices (TE) and organic photovoltaic devices (OPVs). Alongside the increase in performance, the area of sustainability is becoming crucial due to increasingly stringent health and safety regulatory measures. Efforts to integrate sustainable practices into organic electronics research and technology have started to become evident. For example, the efficient synthesis of materials that meet the criteria of green chemistry for clean and low-carbon synthesis should play a key role in this development. In addition, efforts must be made to incorporate materials from renewable resources into devices for a sustainable approach in terms of energy consumption and waste disposal, compared to conventional methods. The aim of this Summer School is therefore to stimulate discussion on the subject of sustainable organic electronics by bringing together internationally recognized experts in their field of expertise. »
