将光致变色分子引入有机/无机杂化材料中可以得到光响应体系。在这样的系统中，二阶非线性特性可以通过适当波长的光的外部刺激来控制。通过在Si（111）上制备含有自组装单层的光致变色分子开关，我们可以证明有效的可逆开关，这伴随着系统的非线性光学（NLO）响应的显著调制。利用功能化的光开关硅表面的概念可能是一种方法，用于生成二维非线性光学开关材料，这是有前途的应用在光子和光电器件。
Incorporating photochromic molecules into organic/inorganic hybrid materials may lead to photoresponsive systems. In such systems, the second-order nonlinear properties can be controlled via external stimulation with light at an appropriate wavelength. By creating photochromic molecular switches containing self-assembled monolayers on Si(111), we can demonstrate efficient reversible switching, which is accompanied by a pronounced modulation of the nonlinear optical (NLO) response of the system. The concept of utilizing functionalized photoswitchable Si surfaces could be a way for the generation of two-dimensional NLO switching materials, which are promising for applications in photonic and optoelectronic devices.
