Understanding the nature of these interactions can provide the basis for regulating their structures and functionalities and a reasonable way to interpret the differences in various properties. However, the relative strength of gold–chalcogen bonds remains controversial, and the conclusions of many related works are inconsistent. Thus, in this work, we successfully quantified the relative strengt...

Jiahao Xia, Peng Zhao, Ke Zheng, Chenjie Lu, Shouchun Yin and Huaping Xu Angew. Chem. Int. Ed., 2019, 131, 552-556. Surface modification is an important technique in fields, such as, self‐cleaning, surface patterning, sensing, and detection. The diselenide bond was shown to be a dynamic covalent bond that can undergo a diselenide metathesis reaction simply under visible light irradiation. Herein we develop this diselenide dynamic chemistry into a versatile surface modification method with a fast response and reversibility. The diselenide bond could be modified onto various substrates, su...
