Abstract

In these ten years after the discovery of electronic conduction in liquid crystals, a lot of effort has been made to characterize what the electronic conduction is in liquid crystals, understand the unique characteristics of charge carrier transport found, synthesize new materials having high mobility, and explore potential applications as a quality organic semiconductor. Judging from the accumulated data and understandings on properties in liquid crystals as a self-organizing molecular semiconductor, it is no doubt that the liquid crystal is very promising as a new type of quality organic semiconductor for opto-electronic devices, which enjoys both merits in molecularly disordered and ordered materials, i.e., large-area uniformity and high mobility that characterize each material, respectively. In this article, the new results found in this decade on charge carrier transport properties, new materials having a high mobility, theoretical modeling of charge carrier transport, which provides us with the physical basis to understand the unique features of charge carrier transport and with the scope and limitation of liquid crystals as an organic semiconductor, are reviewed briefly, and what the further study needs to be focused on for practical device applications are discussed.
