含有2，4-二苯基苯基取代基的二芳基乙烯衍生物形成稳定的无定形固体，表现出可逆的固态光致变色。非晶薄膜的折射率随着光致变色反应可逆地变化，在817 nm处Δ tan = 0.028。吸收带和静态极化率的变化有助于大的折射率调制。
Photochromic diarylethene derivatives containing 2,4-diphenylphenyl substituents formed stable amorphous solids and showed reversible solid-state photochromism. Refractive indices of the amorphous films changed reversibly with the photochromic reactions as much as Deltan = 0.028 at 817 nm. Changes in both absorption band and static polarizability contributed to the large refractive index modulation.
