Abstract
Compounds having two reactive functional groups are described that can be used as a tethering compound to immobilize an amine-containing material to a substrate. The first reactive functional group can be used to provide attachment to a surface of a substrate. The second reactive functional group is a N-sulfonyldicarboximide group that can be reacted with an amine-containing material, particularly a primary aliphatic amine, to form a connector group between the substrate and the amine-containing material. The invention also provides articles and methods for immobilizing amine-containing materials to a substrate.
