We show that the incorporation of chiral bioinspired photochromic compounds into inherently chiral DNA matrices enables the building of smart nanoscale photoswitchable chiroptical assemblies tunable over a wide range of wavelengths. Moreover, the use of light as external trigger affords precise control of the resulting hybrid DNA nanostructures, and their chiroptical activities can be spatially modulated without photochemical fatigue.
我们表明，将手性生物启发光致变色化合物掺入固有手性 DNA 基质中，能够构建智能纳米级光致可调手性组装体，其可调谐波长范围很宽。此外，光作为外部触发可精确控制所得杂交 DNA 纳米结构，并且其手性活性可以在不发生光化学疲劳的情况下进行空间调节。
