| 摘要: 为了提高产率,以5,6-二胺-1,10-邻菲咯啉与1,10-邻菲咯啉-5,6-二酮反应,合成了配体四吡啶[3,2-a:2′,3′-c:3″,2″-h:2"',3"'-j]吩嗪(tpphz)。以此配体为桥合成了钴(Ⅲ)、镍(Ⅱ)为中心金属的三种新的双核配合物。用元素分析、红外光谱、质子核磁共振、热重分析、中心金属滴定等手段对配合物进行了结构表征,并研究了其紫外和荧光光谱性质。 |

| Abstract: Systems containing multifold chromophoric and electroactive centers can be applied as the construction of molecular devices, which include nanometric and well-designed molecular architectures. Owing to the relatively rich photochemical and photophysical properties, transitional metal dendrimers have been tried to apply in the photoconversion and light-harvesting devices. Especially for the Os, Ru complexes, there are many studies on their multi-electron transfer system, which have put solid base for the long-distance electron and energy transfer. But most of the systems studied up to now are linear molecules. The main drawback of these system is the possible rotation around theσ-bonds which decreases the long-distance electron coupling by loss of coplanearity of aromatic parts. Molecule design can be flexible because of the possible adjustment of central metal and the ligand. Based on the above facts and many experiments, three new dinuclear complexes [(phen)2Co(tpphz)Co(phen)2](ClO4)6·6H2O,(tpphz=[3,2-a:2′,3′-c:3″,2″-h:2"',3"'-j])[(bpy)2Ni(tpphz)Ni(bpy)2](ClO4)4·6H2O,[(phen)2Ni(tpphz)Ni(phen)2](ClO4)4·6H2O were synthesized, and characterized by elemental analysis, IR, 1H NMR, and their UV and luminescence spectroscopic properties were studied. The following studies on their long distance charge and energy transfer are in progress. |
