合成了一系列新的偶氮苯二聚体，并将其掺杂到蓝相液晶中，以拓宽蓝相液晶的温度范围。研究发现，由于光诱导偶氮苯的异构化作用，BPI不仅可以可逆地控制其反射波长，而且还可以转变为顺相。
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.
