Schiff base of the molecular second-order nonlinear susceptibility
,[link widoczny dla zalogowanych], Corresponding to the maximum absorption wavelength in the range between 316 ~ 346; colors are white or yellow, no absorption in the visible light or absorb it further, after the frequency of the YAG laser 532nm green light not absorbed, the light conversion rates. General meters, said Lu larger the value of organic molecules,[link widoczny dla zalogowanych], the greater the UV maximum absorption wavelength, the deeper the color. Organic Nonlinear Optical Materials solve the nonlinear optical effect to be strong contradiction with the poor light. Schiff alkali second-order polarization properties homes larger and very light color t transmission range is wide, has a good prospect. 5 Conclusion Schiff homes alkaline compounds the maximum charge transfer transition is a 'transition, in ethanol solution the maximum absorption wavelength in the range of 316 ~ 346 Q, second-order nonlinear susceptibility in the range 101' ~ 10esu magnitude strong nonlinear optical activity cutoff wave length of light absorption, is ideal for a class of organic SHG materials. From the structure-activity relations, benzene, aniline mother ends with a donor and acceptor, the electron donor and acceptor electron ability to enhance its ability to increase the length of conjugated chain molecules, are conducive to molecular nonlinear enhanced optical activity.
