| 제목 | Functionalization of Carbon Nanotubes (CNTs) via Friedel-Crafts Acylations in Polyphosphoric Acid |
| 초록 | Functionalization onto electron deficient carbon nanotubes (CNTs, diameters: 10 and 100 nm) was accomplished via Friedel-Crafts acylation with 2,4,6-trimethylphenoxybenzoic acid (TMPBA) and 4-fluorobenzoic acid (FBA) in polyphosphoric acid using the improved conditions that we previously described.1 The progress of the reaction was conveniently monitored with FT-IR spectroscopy following the growth of the keto-carbonyl band around 1665 cm-1 associated with the product.2 In addition to scanning electron microscopic (SEM), tunneling electron microscopic (TEM), UV-vis spectroscopic data, the combined results from the elemental analysis and thermogravimetric analysis further suggested that aryl carbonyl groups indeed covalently attached to the surface of CNTs. Based on TGA analysis, 38 wt% of TMPBA was attached to the TMPBA-g-CNT (diameter: 100 nm). In the case of FBA-g-CNTs, 3-5 wt% of FBA was attached. They are to be used for further modification of functionalized CNT via aromatic nucleophilic substitution reaction to alter their physical properties. References 1. Baek, J.-B.; Tan, L.-S.
