Jh. Wang et al., Synthesis and characterization of a novel styrylthiophene monomer and corresponding polyurethane for NLO materials, CHIN J POLY, 17(4), 1999, pp. 359-365
A novel monomer, (trans)-7-[4-N,N-(di-beta-hydroxyethyl) amino-benzene]-eth
enyl-3,5-dinitrothiophene (HBDT), was synthesized and characterized. The de
tails of synthesizing the monomer and prepolymer, polyurethane with the mon
omer covalently incorporated are presented. The prepolymer and polyurethane
exhibited good solubility in common organic solvents. Molecular nonlinear
optical properties of the monomer (HBDT) substituted thiophene based stilbe
nes is presented.
