Organic-inorganic hybrid liquid crystals (LC) that we have developed are nanoparticle-based functional materials showing thermotropic LC behavior and self-organization property. For example, hybridization of organic amino-containing LCs with monodisperse needle-like TiO2 nanoparticles (NPs) lead to the introduction of thermotropic liquid-crystallinity. We also succeeded in introducing thermotropic liquid crystallinity into fine monodisperse -Fe2O3 NPs. Recently, we have also developed LC organic-inorganic hybrid dendrimers, where the dendrimer has a spherical gold NP at its core. Dense surface modification of spherical gold NPs with LC dendron was found to result in a hybrid exhibiting a thermotropic LC phase with a simple cubic structure. Furthermore, we focus on imparting such ability to self-organize onto monodisperse quantum dots (QDs) NPs. As a result, dendron-modified QDs were obtained, displaying ordered superlattices. Such structures were found to exhibit unusual photoluminescence behaviour. The details will be discussed in the seminar.
