and nonlinear optical properties of several new multi-octupolar tris(bipyridine) ruthenium complexes are reported. The preparation on these complexes is based on the initial construction of multipodal 4,4'-dialkylaminostyryl-2,2'-bipyridine ligands (DAAS-bpy). Thermally stable polyimides featuring octupolar ruthenium trisbipyridyl complexes have been readily obtained by a polycondensation reaction. The
报道了几种新的多八极三(联吡啶)钌配合物的合成、光物理和非线性光学特性。这些复合物的制备基于多足 4,4'-二烷基氨基苯乙烯基-2,2'-联吡啶配体 (DAAS-bpy) 的初步构建。以八极三联吡啶配合物为特征的热稳定聚酰亚胺已通过缩聚反应容易地获得。二足和三足联吡啶与钌 (II) 的受控配位策略也已成功用于构建双金属、三金属以及第一个由七个金属八极组成的金属树枝状聚合物。这些多金属物质在可见光和长寿命发光中表现出非常强的吸收带。这些大分子的二次 NLO 敏感性 beta 的特点是谐波光散射在 1.91 microm 并与相应的单金属物种的那些进行比较。NLO 研究清楚地证明了金属树枝状聚合物中的准超分子排序。
