Abstract
A method for immobilizing an amino-containing material to a substrate is described. The method involves providing a tethering compound with two reactive groups: a substrate reactive group and a fluoroalkoxycarbonyl group. The method further involves preparing a substrate-attached tethering group by reacting the substrate reactive group of the tethering compound with a complementary functional group on the surface of a substrate. The substrate-attached tethering group has a fluoroalkoxycarbonyl group that can be reacted with an amino-containing material to form an immobilization group that connects the amino-containing material to the substrate.
