Description
Summary:[Display omitted] ► Four ferrocenyl Schiff bases were designed and synthesized. ► The third-order nonlinear optical properties were measured using DFWM. ► The third-order susceptibilities of the compounds were 2.21–3.32×10−13esu. ► The second-order hyperpolarizabilities of the molecules were 2.10–3.15×10−31esu. ► The response times were 42–63fs. Four ferrocenyl Schiff bases were synthesized from ferrocenecarboxaldehyde and aromatic amine. The yields were 46–73%. These compounds have a D-A structure and third-order nonlinear optical (NLO) properties. The third-order nonlinear optical properties of the compounds were measured using femtosecond degenerate four-wave mixing. The third-order NLO susceptibilities of the compounds were 2.21–3.32×10−13esu. The second-order hyperpolarizabilities of the molecules were 2.10–3.15×10−31esu. The response times were 42–63fs.
