Abstract:

There is a growing demand to attain organic materials with high electron mobility, me, as current reliable reported values are significantly lower than those exhibited by their hole mobility counterparts. In this seminar, it will be shown that a well-known non-fullerene-acceptor commonly used in organic solar cells, i.e. BTP-4F (Y6), enables solution-processed organic thin-film transistors (OTFTs), with a me as high as 2.4 cm2·V-1·s-1. This value is comparable to those of state-of-the-art n-type OTFTs, opening up a plethora of new possibilities for this class of materials in the field of organic electronics. Such efficient charge transport is linked to a highly ordered crystalline phase and to peculiar microstructural properties. The interest now is focused on the question if structurally ordered non-fullerene acceptors can exhibit intrinsically high mobility. This would introduce a new approach in the quest of high me organic materials, as well as new guidelines for future materials design.

Bio:

Edgar Gutiérrez Fernández holds a post-doctoral position at POLYMAT in San Sebastian under the supervision of Dr. Jaime Martín. Edgar was born in Madrid and received his BSc. in Physics from the Complutense University of Madrid in 2015. He completed his PhD in the “Soft and Polymeric Matter” group, led by Professor Tiberio Ezquerra, where he specialized in the physics of polymeric materials, especially those connected with the field of organic electronics. He has extensive experience on the application of synchrotron X-ray scattering techniques and fast-scanning calorimetry for the microstructural characterization of conjugated polymers and semiconducting small molecules.
