摘　　要：以2-甲基-8-羟基喹啉和邻苯二胺为原料,合成了一种新的含N,N,O-的三齿配体——2-苯并咪唑-8-辛氧基喹啉(BIQQ)。用2,2'-联吡啶作为第1配体,用2-苯并咪唑-8-辛氧基喹啉(BIQQ)为第2配体,合成了一种新的钌配合物-[R(II)(bpy)2BIOQ][PF6]2。测试表明:这种配合物的熔点为299～300℃,分解温度为299℃;在固体状态下,其光致发光谱为450nm;具较好的热稳定性和荧光性能。最后分析了其在防伪包装方面的应用前景。A new N, N, O-tridentate chelate ligand, namely 2-（benzimidazol-2-yl）-8-octyloxy quinoline （BIOQ）, was synthesized with 8-hydroxyquinadine and o-phenylenediamine as the starting materials. A novel luminescent Ru （II） complex ER （II） （bpy）2 BIOQ][PF622 was synthesized with bpy （（bpy= 2, 2＇-bipyridine） as the first ligand and 2-（benzimidazol-2-yl）-8-octyloxyquinoline （BIOQ） as the second ligand. The test showed that this Ru（II） complex exhibited relatively high thermal stability with a melting point of 299~300 ~C and a decomposition temperature （onset） of 299℃. The photoluminescent spectrum of the complex in solid state ex hibited a strong emission band at 450 nm. At the same time, the applied prospect of complex was studied in anti-counterfeiting packages.
