Untitled | |
Abstract |
The immobilized silica gel ligand systems made by modification of silica surfaces have been briefly summarized. Short background was described based on the synthesis methods and their applications. In this review more attention towards the functionalized polysiloxane xerogels and their postmodification has been given. Polysiloxane-immobilized ligand systems bearing organofunctionalized ligand groups of general formula P–(CH2)3–X (where P represents a three-dimensional silica like network-matrix and X is an organofunctional group) were prepared through the sol–gel process by hydrolytic polycondensation of Si(OR)4 and the appropriate silane coupling agent (RO)3Si(CH2)3X (where R is an alkyl group, e.g CH3 or C2H5). There are many other immobilized ligand systems, which were prepared by treatment of post-polysiloxane precursors with an appropriate organofunctional ligand. Variety of … |
