Photogenerated Base as Catalyst for Imidization Reactions: Design of Photosensitive Polyimides

Abstract

The photogeneration of free amines or diamines from soluble organic precursors such as photoactive 2-nitrobenzyl carbamates is useful for the imidization of polymers containing amic acid or amic ester groups as part of their main-chain or their side-chain. The base-catalyzed reaction occurs at lower temperatures than the noncatalyzed thermal process and is applicable to the patterning of thin film coatings.
