Unique double discotic D-A-D type molecule with exceptional out-of-plane mobility

The proposed experiment is focused on investigation of microstructure and thermal properties of an organic “double discotic” semiconductor with exceptional in-plane and out-of-plane charge mobility. We are planning to perform microfocus diffraction experiments combined with ultrafast heatings and coolings of thin films to determine thermal regimes for formation of columnar liquid-crystalline (LC) phase with conjugated junctions between neighbouring columns. These junctions provide formation of a continuous conjugated network in LC phase that is the reason for unusually high out-of-plane charge carrier mobility.
