Two new ruthenium(II) complexes of formula [Ru(bpy)2(L1)][PF6] and [Ru(bpy)2(L2)][PF6]2 are reported. HL1 is a (nitrophenyl)ethenyl-substituted phenylpyridine ligand, and L2 is the bipyridine analogue of HL1. The X-ray crystal structure of [Ru(bpy)2(L1)][PF6] has been solved, and the compound is found to crystallize in the monoclinic C2/c space group. The electronic spectrum of the cyclometalated derivative
报告了两种新的钌 (II) 配合物 [Ru(bpy)2(L1)][PF6] 和 [Ru(bpy)2(L2)][PF6]2。HL1 是(硝基苯基)乙烯基取代的苯基吡啶配体,L2 是 HL1 的联吡啶类似物。[Ru(bpy)2(L1)][PF6] 的 X 射线晶体结构已被解析,发现该化合物在单斜 C2/c 空间群中结晶。环金属化衍生物 [Ru(bpy)2(L1)][PF6] 的电子光谱表现出一个低位跃迁,相对于基于双吡啶的母体络合物的电子光谱从 454 nm 红移到 546 nm,这揭示了重要的电荷转移特性。为了支持这一假设,通过超瑞利散射技术研究了非线性光学特性,并表明分子静态超极化率 (β0) 等于 230 × 10–30 cm5 esu-1。(© Wiley-VCH Verlag GmbH & Co.
