通过将具有介晶核的有机胺与针状各向异性TiO 2粒子杂化，通过氨基在TiO 2表面的吸附，制备了一种新型的有机-无机杂化热致液晶（LC）。该混合LC在很宽的温度范围内显示出双相。变温小角X射线测量表明，在亚微米尺度上的针状粒子的一维有序的形成诱导热致液晶性。这种技术将导致在无机颗粒中诱导动态功能。
A novel organic-inorganic hybrid thermotropic liquid crystal (LC) is developed by the hybridization of an organic amine with a mesogenic core and an acicular anisotropic TiO2 particle through the adsorption of the amino group to the surfaces of the TiO2. The hybrid LC shows nematic phases in wide ranges of temperatures. Variable-temperature small-angle X-ray measurements reveal that the formation of the one-dimensional nematic order of the acicular particles on a submicrometer scale induces thermotropic liquid crystallinity. This technique would lead to induction of dynamic functions in inorganic particles.
