The number of n-type liquid crystalline semiconductors has been limited. We have already reported that perylene tetracarboxylic bisimide derivatives bearing oligosiloxane chains exhibit columnar phases and efficient electron transport characteristics at room temperature. In this study, we synthesize PTCBI derivatives having various alkyl spacers and oligosiloxane chains and investigate the influence of the length of alkyl spacers and branching pattern of oligosiloxane chains on their mesomorphic properties and carrier transport characteristics.
