A multi-stable and electrically switchable cholesteric liquid crystal based on chiral ionic liquid is demonstrated. The cholesteric liquid crystal can be switched among the planar texture, focal conic texture, wide-band reflected state, and fingerprint texture by applying specific electric fields. Each of these four states exists stably for several hours without any obvious change observed at room temperature. The electro-optical properties and driving scheme of the cholesteric liquid crystal are also reported.
展示了一种基于手性离子液体的多稳态且可电切换的胆甾相液晶。通过施加特定电场，该胆甾相液晶可在平面织构、焦锥织构、宽带反射状态和指纹织构之间切换。在室温下，这四种状态中的每一种都能稳定存在数小时，未观察到任何明显变化。还报道了胆甾相液晶的电光性质和驱动方案。
