The nonlinear second-order optical susceptibilities β_x of some substituted benzenes: aniline, nitrobenzene, o-nitroaniline, p-nitroaniline and 2,4-dinitroaniline were calculated. Then the effects of charge transfer between substituted groups on molecular nonlinear second-order optical susceptibilities were discussed. The conclusion is thatβ′=β_(add)+β_(ct) is not a good formula for the calculation of β, although the idea of contribution of charge transfer...

The nonlinear second-order optical susceptibilities β_x of some substituted benzenes: aniline, nitrobenzene, o-nitroaniline, p-nitroaniline and 2,4-dinitroaniline were calculated. Then the effects of charge transfer between substituted groups on molecular nonlinear second-order optical susceptibilities were discussed. The conclusion is thatβ′=β_(add)+β_(ct) is not a good formula for the calculation of β, although the idea of contribution of charge transfer between substituted groups for β is still a considerable useful concept.

计算了苯胺、硝基苯、邻硝基苯胺、间硝基苯胺、对硝基苯胺及2,4-二硝基苯胺的二阶非线性光学系数β_2,讨论了取代基间电荷转移对分子二阶非线性光学系数的影响。得知β′=β_(add)+β_(ct)不是很好的计算公式,但考虑取代基间的电荷转移对β的贡献仍有其价值。

We also design a molecule with the biggest second-order NLO susceptibility βx. All calculated results are in good agreement with experimental...

On the basis of AMI and INDO/CI methods, according to the sum-over-states expression, we devised a program for calculating nonlinear second-order optical susceptibilities βijk and performedrelevant study of molecular design, i. e. , on the basis of we examined theeffect of different substituents introduced into the phenyl and quinonoid rings, on the second-order optical nonlinearity. It was concluded that introducing a donor into the phenyl ring leads to the increase of β and introducing an acceptor into the phenyl ring leads to a reduction of β; in contrast with this, in troducing a donor in the quinonoid ring leads to the reduction of β and introducing an acceptor in quinonoid ring leads to the increas of β. The regularity summarized from above results has been explained micromechanically. Finally, two molecules having larger nonlinear second-order optical susceptibilities have been designed.
