Abstract
A novel (Trans)-7-[4-N,N-di-((beta) -hydroxyethylamino benzene)] ethenyl 3,5-dinitrothiophene(HBDT) monomer was synthesized and characterized. We also present in this paper an approach to synthesized processible, un-cross-linkable, and thermally stable heterocyclic polymer (Polyurethane) with the monomer covalently incorporated. The details of synthesizing the monomer and un-cross-linked heterocyclic polymer are presented. The un-cross-linked polymer exhibited good solubility in common organic solvents, permitting processing relevant to device fabrication. After being efficiently poled and cured, optical-quality films exhibited moderate nonlinearity and thermal stability.
