| Abstract: | A simple method to disperse carbon nanotubes (CNTs) has been achieved, which gives two photofunctionalized CNTs, hydrazine nanotubes (h-CNTs) and 1,3,4-oxadiazole nanotubes (o-CNTs). Results from FTIR, 1H NMR spectroscopy and TEM observations showed that the functionalization was successful. The modified nanotubes can dissolve in most of the nonpolar organic solvents and no precipitate was observed in the solution of the nanotubes even after 2 months. The functionalized nanotubes showed photo-electronic properties, which is due to the attachment of the function groups to them as proved by steady-state fluorescence spectroscopy. Both h-CNTs and o-CNTs showed good thermal stability below 300 °C and might be used as functional materials. |
