合成了三-(1,10-邻菲啰啉)钌发光配合物Ru(phen)3(PF6)2(phen=1,10-邻菲啰啉),得到了其单晶结构.单晶结构分析结果表明,Ru(phen)3(PF6)2具有层状结构特征,阳离子[Ru(phen)3]^2+和阴离子PF6^-分别构成了正电荷层和负电荷层,正、负电荷层交替排列形成了晶体结构.分别以Ru(phen)3Cl2和Ru(phen)3(PF6)2制备了单层结构的电化学发光器件(LECs),器件结构为[ITO/Ru(Ⅱ)-配合物(100nm)/Al(200nm)].结果显示:以Ru(phen)3(PF6)2为发光层的器件显示的最高效率和亮度分别为0.24cd/A和1829cd/m^2,而以Ru(phen)3Cl2为发光层的器件显示的最高效率和亮度分别为0.18cd/A和350cd/m^2,表明Ru(phen)3(PF6)2比Ru(phen)3Cl2具有更优异的电致发光性能.
Tris (phenanthroline) ruthenium ( Ⅱ ) complex Ru (phen)3 (PF6)2 was synthesized and characterized by X-ray single crystal diffraction. The X-ray diffraction studies revealed that the Ru(phen)3 (PF6)2 has layer structure feature. Cation([Ru(phen)3]^2+)layer and anion (PF6^-) layer arranged alternately resulting in the formation of crystal.Single layer, solid-state light-emitting electrochemical cells with structure of[ITO/Ru(Ⅱ)-complexes(100 nm)/Al (200 nm)] had been prepared based on Ru (phen)3 (PF6)2 and Ru(phen)3 Cl2. The device based on Ru(phen)3 (PF6)2 showed the maximum luminescence was 1 829 cd/m^2 and the maximum current efficiency was 0. 24 cd/A,and that based on Ru(phen)3Cl2 showed the 350 cd/m^2 maximum luminescence and the 0. 18cd/A maximum current efficiency. The results showed that the Ru(phen)3 (PF6)2 is superior to Ru(phen)3Cl2 in the electroluminescent devices.
