Patent ID: 7675058

Claim:
An article comprising: a substrate; a substrate-attached tethering group comprising a reaction product of a complementary functional group G on a surface of the substrate with a compound of Formula I wherein X 1 is a substrate-reactive functional group selected from a carboxy, halocarbonyl, halocarbonyloxy, cyano, hydroxy, mercapto, isocyanato, halosilyl, alkoxysilyl, acyloxysilyl, azido, aziridinyl, haloalkyl, tertiary amino, primary aromatic amino, secondary aromatic amino, disulfide, alkyl disulfide, benzotriazolyl, phosphono, phosphoroamido, or phosphato; Y 1 is a single bond or a divalent group selected from an alkylene, heteroalkylene, arylene, carbonyl, carbonyloxy, carbonylimino, oxy, thio, —NR d —where R d is hydrogen or alkyl, or combinations thereof; Z 1 is (CO)R a wherein R a together with R 1 and groups to which they are attached form a four to eight membered heterocyclic or heterobicyclic group having a nitrogen heteroatom and a sulfur heteroatom, wherein said heterocyclic or heterobicyclic group can be fused to an optional aromatic group, optional saturated or unsaturated cyclic group, or optional saturated or unsaturated bicyclic group; r is equal to 1 when X 1 is a monovalent group or equal to 2 when X 1 is a divalent group; G is the complementary functional group capable of reacting with X 1 to form an ionic bond, covalent bond, or combinations thereof, wherein the group G is selected from hydroxy, mercapto, primary aromatic amino group, secondary aromatic amino group, secondary aliphatic amino group, azide, carboxyl, carboxylic acid anhydride, isocyanate, halocarbonyl, halocarbonyloxy, acrylate, silanol, or nitrile; and said tethering group is unsubstituted or substituted with a halo, alkyl, alkoxy, or combinations thereof.
