Abstract
The present invention relates to a composition including an organic phosphorous-containing group bonded via an oxygen atom to a metal oxide of at least one element M. Generally, the composition is essentially amorphous, and includes an essentially monomolecular layer of an organic group directly bonded to the phosphorous atom. In addition, the composition is generally essentially free of any phosphate, phosphonate or phosphinate phase of the element M. Moreover, the composition has a ratio of the element M to phosphorous of about 15:1-200:1.
Claims19
A composition comprising an organic phosphorous-containing group bonded via an oxygen atom to a metal oxide of at least one element M, the composition being essentially amorphous, comprising an essentially monomolecular layer of an organic group wherein a phosphorous atom of the organic group is directly bonded to an oxygen atom of the metal oxide forming a P—O—M bond, the composition being essentially free of any phosphate, phosphonate or phosphinate phase of the element M, and the ratio of the element M to phosphorus being 15:1-200:1.
