Abstract
The invention is directed to methods for coating monolayer films of surface-active polymers onto substrates of arbitrary shape, and molecular-based methods and processes to control the chemical and physical nature of surfaces and interfaces. The invention is also directed to methods for modifying a surface of a monolayer comprising a) coating a monolayer on a substrate, wherein the monolayer is formed by self-assembly of end-surfactant molecules, thereby positioning a photoactive functional group at the air-monolayer interface; and b) exposing the monolayer to radiation, wherein each organic group of the monolayer contains a first functionality that is not converted to a second functionality upon exposure to acid.
Claims15
A method for modifying a surface of a monolayer, comprising:
- a) coating a monolayer on a substrate;
- wherein the monolayer is formed by self-assembly of end-functionalized surfactant molecules, thereby positioning a photoactive functional group at the air-monolayer interface;
- and
- b) exposing the monolayer to radiation, thereby modifying the surface of the monolayer, wherein the monolayer is a self-assembled monolayer of organic groups comprising a benzophenone moiety, a phthalimide moiety, a benzoin moiety, a photogenerated aldehyde moiety, or a combination thereof, wherein each organic group contains a first functionality that is not converted to a second functionality upon exposure to acid.
