PECASE: Redox-Switchable Catalysis: Concepts and Applications in Polymer Chemistry

Abstract

The goal of this effort was to develop new methods for controlling the structures and properties of macromolecular materials. The general strategy is based on the study of materials that undergo changes in response to various stimuli. One focus of the effort was on demonstration of catalysts that change their activity inresponse to external stimuli. We also studied a class of polymers that respond to stimuli directly including structurally reversible polymers that respond to radiation by undergoing rapid and essentially completed polymerization. Our goal was to exploit these "unzipping" polymers for design of new, very sensitive photoresist formulations that are useful for high resolution EUV and electron beam lithography. We also set out to establish a safe, living anionic polymerization methodology that allows the synthesis of new block copolymers. This methodology has been exploited to prepare block copolymers that spontaneously assemble into useful structure upon interaction with stimuli.
