A new electro-optical chromophore with 4-(bis(2-hydroxyethyl)amino)-2,6-dipropoxybenzaldehyde as electron donor was synthesized and characterized by 1H NMR and mass spectra. Poly(methyl methacrylate) doped with this new chromophore at different loading densities was prepared in thermo-optical films by spin coating. These films showed low optical absorption at communication wavelength, good thermal stability and large thermo-optics coefficients.
