项目摘要

It is an attractive approach to construct a new photoreaction system in connection with the light-triggered molecular devices. We recently reported the photochemical substitution reactions of the ruthenium(II) complexes containing tetradentate Schiff base ligands. In this work, we report the bidirectional photo and thermal substitution reactions of ruthenium(II) complexes containing Schiff base ligands.The tridentate Schiff base ligands were prepared by the reaction of 2-diphenylphosphinobenzaldehyde and 2-hydroxyethylamine or its derivative in ethanol. Equimolecular quantities of [RuClィイD22ィエD2(PPhィイD23ィエD2)ィイD23ィエD2] and ppb-etol (N-(2-diphenyl-phosphinobenzilidene)-2-hydroxyethylamine) were dissolved in dichloromethane and refluxed for 8 h. Red-orange crystals of [RuClィイD22ィエD2(ppb-etol)(PPhィイD23ィエD2)ィイD23ィエD2] (1) were obtained from a dichloro-methane-hexane solution. In acetonitrile, the chrolo ligands of complex 1 are substituted with the solvent molecules to yield an equilibrium mixture of [RuClィイD22ィエD2(CHィイD23ィエD2CN)(ppb-etol)(PPhィイD23ィエD2)ィイD23ィエD2]Cl (2) and [RuClィイD22ィエD2(CHィイD23ィエD2CN)(ppb-etol)(PPhィイD23ィエD2)ィイD23ィエD2]ClィイD22ィエD2 (3) at 50℃ in the dark. The reaction is accompanied by a color of the solution reverts to orange, and complexes 2 and 3 are converted again into complex 1. The color change can be made repeatedly and a reversible photochromic reaction system is constructed.We also reported about the structures and reactives of the pentadentate Schiff base-ruthenium (II) complexes.
结合光触发分子器件构建新的光反应体系是一种有吸引力的途径。我们最近报道了含有四齿席夫碱配体的钌(II)配合物的光化学取代反应。本文报道了含有希夫碱配体的钌(II)配合物的双向光取代和热取代反应。以2-二苯基膦苯甲醛与2-羟乙胺或其衍生物在乙醇中反应制备了三齿希夫碱配体。在二氯甲烷中溶解等量的[RuCl D22 D2(PPh D23 D2) D23 D2]和ppb-乙二胺(N-(2-二苯基-膦苯二胺)-2-羟乙胺),回流8小时。从二氯甲烷-己烷溶液中得到[RuCl D22 D2(PPh D23 D2) D23 D2](1)的红橙色晶体。在乙腈,chrolo复杂1的配体是取代与溶剂分子产生一个平衡的混合物(RuClィイD22摊位ィエD2 (CHィイc15ィエD2CN) (ppb-etol) (PPhィイc15ィエD2)ィイc15ィエD2] Cl(2)和(RuClィイD22摊位ィエD2 (CHィイc15ィエD2CN) (ppb-etol) (PPhィイc15ィエD2)ィイc15ィエD2] ClィイD22摊位ィエD2(3)在黑暗中在50℃。该反应伴随着溶液的颜色恢复为橙色,配合物2和3再次转化为配合物1。可重复变色,构建了可逆的光致变色反应体系。我们还报道了五齿基希夫碱钌(II)配合物的结构和反应。
