The synthesis and spectral and structural characterization of a new family of ruthenium(II) complexes containing 3-bromo-, 3,8-dibromo-, 3-(thiophen-2′,2″-yl)-, and 3,8-(thiophen-2′,2″-yl)-1,10-phenanthroline (phen) ligands is described. UV/Vis spectroscopy is used to compare the differences between the conjugated π systems in these ligands and their respective [Ru(bpy)2]2+ (bpy = 2,2′-bipyridine)
包含 3-溴-、3,8-二溴-、3-(噻吩-2',2″-基)-和 3,8- 的新型钌 (II) 配合物家族的合成、光谱和结构表征描述了 (thiophen-2',2"-yl)-1,10-菲咯啉 (phen) 配体。紫外/可见光谱用于比较这些配体中共轭 π 系统与其各自的 [Ru(bpy)2]2+ (bpy = 2,2'-联吡啶) 类似物之间的差异。已经进行了密度泛函理论 (DFT) 计算以比较单晶和能量最小化结构之间的能量差异对于噻吩环及其键合的不同构象(反式/反式、反式/顺式和顺式/顺式)芬环。通过原位电聚合形成低聚噻吩半导体聚合物,桥接金电极与 RuII 配合物 7 之间的间隙约为 25 nm,通过扫描电子显微镜 (SEM) 监测其去除情况。(© Wiley-VCH Verlag GmbH & Co.
