A new series of azobenzene-dimers were synthesized and doped into the blue phase liquid crystals to broaden the temperature range of BPs. It is found that not only can the reflection wavelength of BPI be reversibly controlled but BPI can also be transformed into the cholesteric phase owing to isomerization of azobenzene induced by light.
合成了一系列新型偶氮二聚体,并将其掺杂到蓝相液晶中以拓宽 BP 的温度范围。结果发现,不仅可以可逆地控制 BPI 的反射波长,而且由于光诱导的偶氮苯的异构化,BPI 还可以转变为胆甾相液晶。
