Title: Narrow band gap conjugated polymers employing cross-conjugated donors useful in electronic devices

Abstract

The invention provides for new polymer compounds and methods for the preparation of modular narrow band gap conjugated compounds and polymers that incorporate exocyclic cross-conjugated donors or substituents, as well as novel monomer components of such polymers and the resulting products which comprise materials and useful electronic devices with novel functionality.
