我们研究了含有偶氮苯部分的光响应离子液体。含对，对′-偶氮苯或邻，对′-二偶氮苯的离子液体在光和热刺激下表现出可逆的固-液相变。作为具有弯曲结构的离子液体存在的邻，对偶氮苯甚至作为反式异构体处于液态。这种光响应性离子液体可用作新型功能材料，例如在光学传感器中。
We examined photoresponsive ionic liquids containing an azobenzene moiety. Ionic liquids with a p,p'-azobenzene or o,p'-tetrafluoroazobenzene moiety exhibit a reversible solid-to-liquid phase transition induced by photo- and thermal-stimulation. o,p'-Azobenzene, which exists as an ionic liquid with a bent structure, is in a liquid state even as a trans-isomer. Such photoresponsive ionic liquids may be useful as novel functional materials, such as in optical sensors.
