    The adsorption and immobilization of tris(2,2′-bipyridine)-ruthenium(II) ([Ru(bpy)3]2+) in mesoporous silicas (C18-FSM) modified by the introduction of aluminum as well as sulfonic acid groups were investigated. The complex was immobilized by the cooperative effects of electrostatic interactions between [Ru(bpy)3]2+ cation and sulfonic acid group and the interactions with the phenyl rings of the mesopore surface and the bipyridine rings.
