SCL group activity
The group “Linear Conjugated Systems” (SCL) includes specialists in organic synthesis and physical chemistry (CNRS section 13 and sections CNU 31-32).
The activity of the team is focused on the design, synthesis, characterization and applications of molecules, molecular assemblies and materials from conjugated systems.
This activity is divided into 5 main areas:
Nano-dynamic objects
Surface modification
Electronic devices and organic solar cells
Semiconductors from biomass
Materials for electrodes and functionalized surfaces
All these activities rely on a proven experience and on many fundamental studies
on structure-property relation-ships in organic electro-active conjugated system..
Surface modifications
Two-dimensional organic networks as host for electroactive molecules
Nano-objects
Synthesis of nano-objects that can mimic logic circuits by photoswitching. Models for the future design of molecular electronic devices.
Organic electronics and solar cells
Design, synthesis and study of new organic chromophores incorporable as active materials in solar cells and in other electronic devices.
Use of small molecules in place of polymers in solar cells.
Semi-conductors from biomass
Renewable raw materials derived from biomass for organic electronics.
Matérials for electrodes
Functionalized electroactive polymers as sensors or for storage and release of organic compounds or gases.
