Synthesis of diamine terminated poly(ethylene glycol) and steric stabilization of multiple-walled carbon nanotube (MWNT)

초록

The hydroxyl end groups of poly(ethylene glycol) (PEG) have been transformed easily and quantitatively into amino groups via the Mitsunobu reaction. Phthalimide was alkylated with PEGs and the hydrazinolysis of the resulting phthalimido-PEGs gave the amino compounds in high yields. The amino-PEGs exhibit attractive properties for the steric stabilization of carbon nanotubes.
