Determining exact molar absorbance coefficients of single-wall carbon nanotubes
文献信息
Shota Kuwahara, Hisanori Shinohara
A new spray technique coupled with atomic force microscopy is developed to obtain the absolute number of carbon nanotubes in a unit volume. By using the present technique, the absolute molar absorbance coefficient of single-wall carbon nanotubes (SWNTs) has been determined and found to be ca. 2–5 × 107 L mol−1 cm−1. This molar absorbance coefficient enables us to deal with carbon nanotubes as individual “molecules” and to adequately compare them with other related compounds such as fullerenes. The absorbance coefficient of SWNTs is found to be only 100 times as large as those of fullerenes. This indicates that the large aspect ratio, random orientation in dispersion solution and anisotropic absorption properties of SWNTs substantially reduce their absorption probability.

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.
