Invited webinar - New electrically and optically active molecular materials...- by Giulia Pancotti

"New electrically and optically active molecular materials characterized by synchrotron Circular Dichroism" presented by Giulia Pancotti, Institut de Ciència de Materials de Barcelona (ICMAB-CSIC), Spain;  Chaired by Dr. Sara Battista, Institut de Ciència de Materials de Barcelona (ICMAB-CSIC), Spain

The phenomenon known as “supramolecular chirality”, whereby the optical properties of a chiral object are transferred, in some extents, to higher order supramolecular structures, is of particular interest in the development of organic photovoltaic devices (OPVs). Thin films exhibit a close relationship between their supramolecular arrangement and their efficiencies, thereby highlighting the significant role played by the correlation between the chiral supramolecular arrangement and the physical parameters of the devices such as Fill Factor (FF), Open Circuit Voltage (Voc) and Short Circuit Current (Isc).

Additionally, chirality provides the opporunity to employ Circular Dicroism (CD) spectroscopy to employ Circular Dichroism (CD) spectroscopy, which is the preferred method for investigating optical activity .…
