Abstract

Brillouin spectroscopy is commonly used to study the acoustic properties of materials. Here we explored its feasibility in studying the photoinduced isomerization of azobenzene. The isomerization of azobenzene changes the solution elastic modulus, and Brillouin scattering is sensitive to these changes. In this study, we experimentally demonstrated the photoswitching of azobenzene in DMSO using our home-made virtually imaged phased array-based high-resolution optical Brillouin spectrometer, and confirmed the results by ultraviolet–visible spectrophotometry. Remarkable Brillouin frequency shift variations were quantitatively recorded upon irradiation, and it was found that this method can indeed be used to monitor the isomerization process in situ. Importantly, our strategy also allows us to provide the relationship between the fraction of trans- and cis- azobenzene and the Brillouin frequency shift. This shows that Brillouin spectroscopy has broad prospects for the characterization of azobenzene isomerization and other photoresponsive materials.

利用布里渊显微镜监测偶氮苯的顺反异构过程
布里渊光谱法通常用于研究材料的声学特性。在此,我们探索了布里渊光谱在研究偶氮苯的光诱导异构化方面的可行性。偶氮苯的异构化会改变溶液的弹性模量,而布里渊散射对这些变化非常敏感。在本研究中,我们利用自制的基于相控阵的虚拟成像高分辨率光学布里渊光谱仪,实验证明了偶氮苯在二甲基亚砜中的光开关现象,并通过紫外-可见分光光度法证实了这一结果。结果发现,这种方法确实可用于原位监测异构化过程。重要的是,我们的方法还能提供反式和顺式偶氮苯的比例与布里渊频移之间的关系。这表明布里渊光谱法在表征偶氮苯异构化和其他光致发光材料方面具有广阔的前景。
