The photoinduced changes in polarity and molecular structure have led to widespread application of azobenzene derivatives as reversible molecular switch devices.

光致极性和分子结构的变化使偶氮衍生物作为可逆的分子开关器件得以普遍应用。

Now what we are hoping to find where the switch is between the reversible and non-reversible forms or to know the molecular mechanisms that lead to this.

现在我们最希望找到从可逆阶段转换到不可逆阶段的分界点以及发生这种转换的分子机制。
