“…[160,161] Free radicals (e.g., 4-methoxyohenyl-free radicals) have also been generated either by air oxidation of 4-methoxyphenylhydrazine hydrochloride [162] or by using a microwave-assisted approach with an optimal reaction time of 5 min. [163] SWNTs have been functionalized via one-electron reduction of benzophenone by potassium. [164] In another related study, irradiation of benzophenone (e.g., an aromatic ketone), benzhydrol, and SWNTs in benzene resulted in covalent attachment of benzhydrol to the sidewalls of SWNTs at a density of 1 molecule per 52 sidewall carbons.…”

In this Progress Report, we update covalent chemical strategies commonly used for the focused functionalization of single‐walled carbon nanotube (SWNT) surfaces. In recent years, SWNTs have been treated as legitimate nanoscale chemical reagents. Hence, herein we seek to understand, from a structural and mechanistic perspective, the breadth and types of controlled covalent reactions SWNTs can undergo in solution phase, not only at ends and defect sites but also along sidewalls. We explore advances in the formation of nanotube derivatives that essentially maintain and even enhance their performance metrics after precise chemical modification. We especially highlight molecular insights (and corresponding correlation with properties) into the binding of functional moieties onto carbon nanotube surfaces. Controllable chemical functionalization suggests that the unique optical, electronic, and mechanical properties of SWNTs can be much more readily tuned than ever before, with key implications for the generation of truly functional nanoscale working devices.

“…With a similar yield of functionalization, the microwave-assisted reaction is far more rapid with an optimal time of around 5 min. This represents a vast reduction in reaction time which for the classical method is often measured in days (Liu, Zubiri et al 2007). On the other hand, Tian (Tian et al 2009) and coworkers have demonstrated a highly efficient approach to prepare the polymer-grafted SWNTs by electrophilic addition with 3-chloropropane based on microwave technique (path B in Fig.…”

“…In case of microwave-assisted functionalization of CNTs, microwave irradiation of CNT reduces the reaction time and gives rise to products with higher degrees of functionalization than those obtained by the conventional thermal methods (Vazquez and Prato 2009). Interestingly, Liu and coworkers (Liu, Zubiri et al 2007) suggest a competitive effect of microwave irradiation that both promotes functionalization and removes some functional groups that are initially present. On the other hand, Vazquez and coworkers show that a solvent-free technique combined with microwave irradiation produces functionalized nanotubes in just 1 h of reaction, paving the way to large scale production of functionalization (Brunetti et al 2007).…”
