螺旋纳米丝（HNFs）由于其独特的光学特性而引起了人们的广泛关注，但由于其结构的复杂性，在实际应用中还存在许多障碍。在这里，我们证明了可以使用物理化学约束系统研究调制的HNF （HNF (mod)）的分子构型和层构象。在表面修饰的纳米通道中，受介质与表面化学亲和力影响的层向受到严格控制。此外，利用掠入射x射线衍射（GIXD）进行了原位实验，详细研究了热转变过程中的结构演变。结果表明，HNF（mod）结构可以很好地用于功能性HNF器件的应用，并且结合化学和物理约束效应的组合系统将有助于更好地理解软物质的基本原理。
Helical nanofilaments (HNFs) have attracted much interest because of their unique optical properties, but there have been many hurdles to overcome in using them for the practical applications due to their structural complexity. Here we demonstrate that the molecular configuration and layer conformation of a modulated HNF (HNFs(mod)) can be studied using a physicochemical confinement system. The layer directions affected by the chemical affinity between the mesogen and surface were drastically controlled in surface-modified nanochannels. Furthermore, an in situ experiment using grazing-incidence X-ray diffraction (GIXD) was carried out to investigate in detail the structural evolution through thermal transitions. The results demonstrate that the HNF(mod) structure can be perfectly controlled for functional HNF device applications, and a combined system with chemical and physical confinement effects will be helpful to better understand the fundamentals of soft matter.
