Synthesis and third-order optical nonlinearities of anthracenedione derivatives

摘要

Six D-pi-A-pi-D anthracenedione derivatives were synthesized and characterized by UV,IR,1H NMR and elemental analysis.The third-order nonlinear optical properties of the compounds were measured using femtosecond degenerate four-wave mixing.The third-order nonlinear optical susceptibilities chi(3) of the compounds were 2.64-3.83 x 10~(-13) esu.The second-order hyperpolarizabilities gamma of the molecules were 2.86-3.84 x 10~(-31) esu.The response times were 86-108 fs.
