带全氟环己烯环的二乙烯在常压下升华形成空心晶体在紫外照射下，晶体表现出显著的光显现象，并分散成小块。紫外光照射下晶体释放出的碎片飞行速度超过每秒几米。为了在更小的尺度上清楚地显示类似凤仙花散射行为的光显效应，将直径为1 μ m的小荧光珠插入空心晶体中。因此，观察到紫外光照射引起空心结构变形和破裂时珠子的散射。这种现象是空心晶体所特有的，有效诱导显光现象的能力与自然界中空心结构凤仙花的行为相似。
A diarylethene with a perfluorocyclohexene ring formed hollow crystals by sublimation under normal pressure. Upon UV irradiation of the crystals, they showed remarkable photosalient phenomena and scattered into small pieces. The speed of the flying debris released from the crystal by UV irradiation exceeded several meters per second. To clearly show a photosalient effect resembling the scattering behavior of Impatiens on a smaller scale, small fluorescent beads (1-mu m diameter) were inserted into the hollow crystal. Consequently, scattering of the beads was observed as UV irradiation caused deformation and bursting of the hollow structure. This phenomenon is unique to hollow crystals, and the ability to effectively induce remarkable photosalient phenomena is similar to the behavior of hollow-structured Impatiens in nature.
