Abstract:
Nonlinear optical azo chromophores with dihydroxylethylamino donors and nitro acceptors were designed and synthesized. The target compounds were characterized by nuclear magnetic resonance(NMR), infrared spectrum(IR), ultraviolet spectrum(UV)and melting point measurement. The decomposition temperature was determined with differential scanning calorimetry, and the absorption spectra were measured. The first molecular hyperpolarizability of 140×10-30esu and 351×10-30esu were acquired through solvatochromic methods. The chromophores were thermally stable up to 291. 93 ℃ and 302. 36 ℃. These nonlinear optical chromophores exhibit large optical nonlinearity and good thermal stability.
