Novel nickel phthalocynaine complexes bearing siloxane moieties were synthesized and their mesomorphic properties and their carrier transport properties were investigated. These compounds showed columnar mesophases over a wide range of temperature including room temperature through nanosegregation between π-conjugated cores and oligosiloxane moieties. Most of the compounds exhibit higher phase transition temperatures to the isotropic phase than that of alkylated compound 1. Moreover, the compounds that show a hexagonal columnar phase form homeotropic alignment in sandwich cells consisting of two ITO electrodes. Therefore, carrier transport property of some compounds could be evaluated by a Time-of-Flight method which revealed that they exhibited ambipolar carrier transport properties in columnar mesophases.
