Deuterated chloroform cdcl3

Unless otherwise stated, all compounds and solvents were purchased from commercial suppliers and used without further purification. SWCNTs (≥90% carbon basis (≥80% as carbon nanotubes), 1.3 nm in diameter) were purchased from Sigma–Aldrich Co., Ltd. (St. Louis, MO, USA). Isopropanol (IPA), dichloromethane, and chloroform (CHCl₃) were purchased from Junsei Chemical Co., Ltd. (Tokyo, Japan). Acetone, hexane, and deuterated chloroform (CDCl₃) were purchased from FUJIFILM Wako Pure Chemical Co., Ltd. (Osaka, Japan). Tetrahydrofuran (THF; spectroscopic grade) was purchased from Kanto Chemical Co., Inc. (Tokyo, Japan). An elastic carbon-coated copper transmission electron microscopy (TEM) grid was purchased from Okenshoji Co., Ltd. (ELS-C10, Tokyo, Japan). A fused silica substrate was purchased from Matsunami Glass Ind., Ltd. (Osaka, Japan).

Nonanoic acid was purchased from Tokyo Chemical Industry (TCI; purity, >98.0%) and Thermo Fisher Scientific Chemicals (purity, 97%). The latter product was identical to the Alfa Aesar product used by Rossignol et al. (6 (link)). As both showed similar UV absorption spectra, we focused on the TCI reagent for purification (fig. S1). Acetonitrile (purity, ≥99.5%, Nacalai Tesque) solvent was used for recrystallization. Octanoic acid (purity, ≥99%) was from Sigma-Aldrich. Deuterated chloroform (CDCl₃; purity, 99.8%) was from Fujifilm Wako Pure Chemical Corporation. Purified liquid H₂O (resistivity, ≥18.2 megohm·cm at 298 K) was obtained from a Millipore Milli-Q water purification system.
