| 摘 要： | The new chromophore molecules with nonlinear optical （NLO） properties were prepared by Knoevenagel condensation from 1,8-dimethoxy-4,5-diformyl-9,10-dihydroanthracene and isophorone derivative in the presence of piperidine and acetic acid. In these chromophore, the ring-locked trienes were employed as the conjugation bridge and electron acceptor in D-π-A units. The key intermediate dialdehyde was conveniently prepared via a three step reaction, in which 1,8-dimethoxyanthraquinone was reduced with zinc/acetic acid and sodium/ethanol successively, followed by formylation with 1,1-dichlorodimethyl ether in the presence of TiCI4. The solvatochromism and UV spectra indicate that they have higher second-order nonlinear hyperpolarizability μβ values than the corresponding reference compound, without red shift of the charge transfer band.

| Abstract: | The new chromophore molecules with nonlinear optical (NLO) properties were prepared by Knoevenagel condensation from 1,8‐dimethoxy‐4,5‐diformyl‐9,10‐dihydroanthracene and isophorone derivative in the presence of piperidine and acetic acid. In these chromophore, the ring‐locked trienes were employed as the conjugation bridge and electron acceptor in D‐π‐A units. The key intermediate dialdehyde was conveniently prepared via a three step reaction, in which 1,8‐dimethoxyanthraquinone was reduced with zinc/acetic acid and sodium/ethanol successively, followed by formylation with 1,1‐dichlorodimethyl ether in the presence of TiCl4. The solvatochromism indicate that they have higher second‐order nonlinear hyperpolarizability μβ values than the corresponding reference compound, without red shift of the charge transfer band. |
