Abstract
Modification of silica with viologenic groups is described. N,N′-Diallyl-γ,γ′-dipyridinium dibromide obtained by the reaction of allyl bromide with γ,γ′-dipyridyl was hydrosilylated with triethoxysilane followed by copolycondensation of the synthesized bis(3-triethoxysilylpropyl)-γ,γ′-dipyridinium dibromide with tetraethoxysilane.
