Separation of metallic and semiconducting single-walled carbon nanotubes (SWCNTs) is of great importance for SWCNT-based nano-electronics. We propose a tandem extraction strategy for efficient separation of different types of SWCNTs. This strategy is based on chiral angle discriminated adsorption of soluble condensed benzenoid aromatic molecules on SWCNTs, which induce different dispersibility of SWCNTs in various organic solvents. The proposed tandem extraction strategy involves two extraction steps, in which the first step extracts metallic SWCNTs with large chiral angles and the subsequent step enriches large chiral angle semiconducting SWCNTs. This separation strategy is tested on a series of condensed benzenoid aromatic molecules. Both experimental and theoretical results show that the separation efficiency is strongly dependent on the molecular morphology, i.e. higher aspect ratio gives better separation results. The separation efficiency is also dependent on the SWCNT diameter and the solvent properties. This tandem extraction strategy may also be applied to other available noncovalent separation reagents to improve their separation efficiency.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
