TitlePolysiloxane-immobilized triamine ligand system, synthesis and applications
Untitled
Abstract

The polysiloxane-immobilized triamine ligand system of the formula P-(CH 2 ) 3 NH(CH 2 ) 2 NH(CH 2 ) 2 NH 2 (where P represents the siloxane network) has been prepared via the sol-gel process by hydrolytic polycondensation of (EtO) 4 Si and (MeO) 3 Si(CH 2 ) 3 NH(CH 2 ) 2 NH(CH 2 ) 2 NH 2 . An alternative method was used by the reaction of the iodopolysiloxane P-(CH 2 ) 3 -I and diethylenetriamine in the presence of triethylamine. The immobilized triamine ligand forms metal chelate complexes when treated with aqueous metal(II) ion solutions (Co 2+ , Ni 2+ , and Cu 2+ ). The elemental analysis and FTIR results suggest that this ligand system undergoes a substantial leaching of diethylenetriamine ligand moieties from the siloxane framework.
