当含有6'-硝基吲哚并螺吡喃的聚(L-谷氨酸)薄膜暴露于紫外光(主要是365nm)时，观察到旋光力发生可测量的变化，并伴随由于光部花青的形成而着色。暴露于可见光（>480nm）后，这种变化是可逆的。发现旋光能力可逆变化的程度取决于螺吡喃的浓度以及浇注浓度。对旋光性出现的机理进行了讨论。
When the thin film of poly(L-glutamate) containing 6′-nitroindolinospiropyran was exposed to uv light(mainly 365nm), measurable change in the optical rotatory power was observed, accompanied with the coloration due to the formation of the photo-merocyanine. The change was reversible upon exposure to visible light(>480nm). The extent of the reversible change of the optical rotatory power was found to depend on the concentration of the spiropyran as well as casting concentration. Discussion was made on the mechanism of the appearance of the optical rotatory power.
