Application

2,2,6,6-Tetramethyl-4-piperidinol has been used to study the green and efficient method for chemoselective deoxidization of graphene oxide via the ultraviolet irradiation.
2,2,6,6-tetramethyl-4-piperidinol has been used to study the irradiation of Camptothecin (CPT) in aerated dimethylsulfoxide (DMSO) solution that leads to formation of singlet oxygen.
Used as:
  • An additive for polymer modified hindered amine light stabilizers
  • A light stabilizer for polyamide 66 fibers containing acid blue dyes

We report a green and efficient method for chemoselective deoxidization of graphene oxide via the ultraviolet irradiation catalyzed with 2,2,6,6-tetramethyl-4-piperidinol. While the sp(2)-hybridized oxygen functional groups are removed after the reduction, the epoxy and hydroxyl groups are retained in the
