Order is amongst the most important parameters that govern the physics of organic semiconductors (OSCs) [1] However,materials must be ordered at all length-scales,from molecular dimensions to macroscopic distances [2].Liquid crystals constitute a unique class of materials that spontaneously self-assembles into single domain thin films with specific alignment [3-5].Patterning of aligned single domains of liquid crystalline OSCs has recently been demonstrated [6,7].Nevertheless,liquid crystalline semiconductors suffer from numerous structural defects created by their partial liquid character and that limit their charge carrier mobility [1,8,9].
