Abstract

A facile synthetic route has been developed to convert an electron-rich, sterically hindered dialkylaminodienone into a conjugated dialkylaminotrienal with good yield. The derived dialkylaminotetraene-type nonlinear optical chromophores possess an all-trans conformation and can be functlonalized with fluoro-dendron to provide proper shape modification for poling. Polymers doped with two examples of these chromophores in high concentrations have been poled to afford ultra-large electrooptic coefficients (r33) of 208 and 262 pm/V, respectively, at the measuring wavelength of 1.31 μm.
