利用螺吡喃的光异构化作用，合成了一种新型的光动力分子穿梭器，它可以在二肽和两性离子ME两个不同的位置之间切换大环的运动。大环以SP形式选择性地驻留在二肽站中，并在UV光照射下移动到ME站。大环的这种运动过程伴随着可由肉眼检测到的可逆吸收输出信号。
A novel light-powered molecular shuttle was synthesized which can switch the movement of a macrocycle between two distinct stations-dipeptide and zwitterionic ME-by exploiting the photoisomerization of spiropyran. The macrocycle resides selectively in the dipeptide station in the SP form and moves to the ME station under the irradiation of UV light. This movement process of the macrocycle is accompanied by reversible absorptive output signals which can be detected by the naked eye.
