设计合成了一系列二核和三核( 金属离子的个数) 钌( Ⅱ) 吡啶和联吡啶混合配体的化合物。利用色谱柱分离法使产物得以有效的分离。这类化合物在组成上具有吡啶和联吡啶两种配体,两组元分别为顺、反结构。这种组成和结构上的特殊性,使得这些化合物的光物理和光化学性质与已有的二核化合物相比,具有独特之处:一个化合物中具有几个不同金属向配体的电子跃迁过程( MLCT) 。它们的IR吸收特征,特别是氰配体成桥后IR 振动频率的变化,证明了二核和三核化合物的形成。所得新化合物具有较强的光致发光性能,在一个化合物中同时具有两个不同波长的发射峰,这一发光特性与它们的二元组成是相对应的。
A series of compounds were designed and synthesized with binuclear and trinuclear (the number of metal ions) ruthenium (Ⅱ) pyridine and bipyridine mixed ligand. The use of column separation products to be effective separation. Such compounds in the composition of pyridine and bipyridine two ligands, two components were cis and trans structure. This compositional and structural specificity makes the photophysical and photochemical properties of these compounds unique compared to existing dinuclear compounds: the electronic transition of several different metals to ligands in one compound ( MLCT). Their IR absorption characteristics, especially the change in the frequency of IR vibration after bridged with cyanide ligand, demonstrate the formation of dinuclear and trinuclear compounds. The new compounds obtained have strong photoluminescence properties. In one compound, they have two different emission peaks at the same time, and their luminescence properties correspond to their binary composition.
