prof.dr. Jean Roncali : Molecular Engineering of Functional pi-Conjugated Systems

When:Tu 24-03-2015 10:00 - 11:00

The control of the electronic properties of pi-conjugated systems represents a key issue for the development of their multiple technological applications as:

·         Electrode materials for energy storage, sensors or electro-catalysis.

·         Molecular architectures for molecular electronics.

·         Active materials for organic light-emitting devices (OLEDs) , field-effect transistors (OFETs) and photovoltaic conversion (OPV).

Since each of these fields of application resorts to specific physical, chemical and electronic properties of the functional molecule and/or material, progress in these various areas requires the definition of appropriate guidelines for the design and synthesis of functional pi-conjugated systems. This objective involves both the tuning of the electronics properties at the molecular level and the control of intermolecular interactions that in fine determine the ultimate collective properties of the active material.

These various aspects of the molecular and supramolecular engineering of functional pi-conjugated systems will be discussed on the basis of selected examples of molecules and materials designed for applications in electrode materials, molecular electronics and OPV.
