Abstract
The invention concerns a method for the chemical modification of a surface based on the reaction of photolytically generated reactive intermediates derived from azido heterocycles with said surface.
Claims21
A method for the chemical modification of a surface which method comprises the photoactivation of an azido heterocyclic compound, containing one or more aromatic rings, in the presence of the surface, to generate a reactive intermediate, followed by the interaction of the photogenerated reactive intermediate with the surface to form a modified surface, wherein said process is carried on in the substantial absence of air and water.
A method for the chemical modification of surfaces in an image wise fashion which method comprises the photoactivation, in an image wise fashion, of an azido heterocyclic compound, containing one or more aromatic rings, in the presence of the surface to generate a reactive intermediate, followed by the interaction of the photogenerated reactive intermediate with the surface in an image wise fashion to form the image wise fashion modified surface, wherein said process is carried on in the substantial absence of air and water.
A method for the chemical modification of a surface comprising the photoactivation of an azido heterocyclic compound, containing one or more aromatic rings, in the presence of the surface to be modified so as to cause the azido heterocyclic compound to modify the surface, wherein said process is carried out in the substantial absence of air and water.
