I would like to give a talk about a precise orientation control of a liquid crystal organic semiconductor (LC-OSC) based on a long-range ordering characteristic of LC material. For this, a synthetic LC-OSC molecule, MeOPh-BTBT-C8 having the fluidic nematic (N) phase that is essential for the alignment control in a large area and the smectic E (SmE) phase showing the high ordering was prepared. Optical observation of the alignment-controlled LC-OSC was carried out by polarized optical microscopy (POM), and the corresponding charge carrier mobility was also measured by fabricating organic field-effect transistors (OFETs). Our platform will propose a facile approach for multi-directional and multi-functional organic electronic devices using stimuli-responsive characteristics of LC materials.
