One-dimensional materials have been intensively studied because of their diverse properties, which are revealed when exfoliated from their bulk precursor. Liquid exfoliation is not only possibly the most suitable method for large-scale applications but also affords an opportunity to develop new deposition techniques. Fibrous phosphorus is a relatively new, one-dimensional material with high carrier mobility and a fast response velocity for future application in nanodevices. Because controllable liquid exfoliation processing of fibrous phosphorus (FP) remains challenging, we considered two factors: the exfoliated result and the removable solvents. We proposed a method for determining suitable solvents for efficient exfoliation and controllable size of fibrous phosphorus using Hansen solubility parameters. By controlling the water/acetone mixture ratios, the exfoliation effect could be controlled. Our work showed that 40% of the FP nanofibers were less than 10 nm in thickness and 70% of them were less than 20 nm. Furthermore, fibrous phosphorus produced a red fluorescence in bioimaging.

纤维磷的可控液体剥落及其活细胞成像

一维材料由于其多样化的特性而受到了广泛的研究，这些特性在从其大量前体中剥落时会显现出来。液体剥落不仅可能是最适合大规模应用的方法，而且还为开发新的沉积技术提供了机会。纤维状磷是一种相对较新的一维材料，具有较高的载流子迁移率和快速的响应速度，可用于将来在纳米器件中的应用。由于纤维磷（FP）的可控液体剥落工艺仍然具有挑战性，因此我们考虑了两个因素：剥落的结果和可去除的溶剂。我们提出了一种使用Hansen溶解度参数确定合适的溶剂以有效剥离和控制纤维磷的尺寸的方法。通过控制水/丙酮的混合比，可以控制剥离效果。我们的工作表明，40％的FP纳米纤维的厚度小于10 nm，其中70％的厚度小于20 nm。此外，纤维状磷在生物成像中产生红色荧光。
