Incorporation of the macrocyclic ligand cucurbituril into a silica matrix
Abstract-The macrocyclic ligand cucurbituril is incorporated into a silica gel matrix using the common sol-gel technique. The distribution of cucurbituril in the silica gel is shown to be homogeneous. The porous structure of the matrix enables complex formation of cucurbituril with organic molecules. This composite is suitable for practical applications in analytical chemistry or for removal of organic pollutants from aqueous solutions.
