设计了一种新型的光响应型三稳手性开关，通过对胆甾相液晶的分段反射调谐，实现了黑底彩色图案。在文献1704941中，余艳雷等人发现，手性开关的三种稳定构型赋予了系统两个连续且相邻的反射调谐周期，不仅覆盖了整个可见光光谱，而且在近红外区还覆盖了更宽的周期。
Colorful patterns with a black background are realized based on piecewise reflection tuning of cholesteric liquid crystals induced by a newly designed photoresponsive tristable chiral switch. In article number 1704941, Yanlei Yu and co-workers find that the three stable configurations of the chiral switch endow the system with two continuous and adjacent tuning periods of the reflection, covering not only the entire visible spectrum, but also a further wide period within near-infrared region.
