| Abstract: | The maximum absorption wavelength (λ_e),absorption coefficient (ε),maximum emission wavelength (λ_e) of azocoumarin compounds were measured,at the same time,the second-order nonlinear polarizabilities (β_(xxx)) of these compounds were determined by solvatochromic method.The results show that these compounds have high values of second-order nonlinear polarizability in solution. |

| Keywords: | azocoumarin second-order nonlinear polarizability solvatochromic method |
