We identified the liquid crystal phase in the aqueous colloid of Ca₂Nb₃O10⁻ nanosheets, which were synthesized by exfoliation of the smiconducting layered perovskite KCa₂Nb₃O₁₀. The nanosheets were obtained in the highest yield when HCa₂Nb₃O₁₀ was allowed to react with the exfoliating reagent (tetrabutylammonium; TBA⁺)in the molar ratio of TBA⁺: HCa₂Nb₃O₁₀＝10:1, followed by washing the sample for 6 times with water. When the nanosheet colloid (1.7wt%) was observed by crossed polarizers, the interference colors due to permanent birefringence was observed; this observation clearly confirmed the liquid crystallinity of this system. On the other hand, birefringence was not observed in the colloid of 0.4wt.%, indicating that the colloid is isotropic. In this dilute colloid, however, birefringence was temporarily observed when the nanosheet colloid was flowed. The liquid crystalline nanosheet colloid absorbed UV light with the wavelength smaller than 280nm, due to the semiconducting property of the nanosheet with the bandgap of 4.4eV.
