中文摘要：

多吡啶钌配合物在光化学、光物理、电化学、电子转移、能量转移、分子组装和分子识别等研究领域都扮演着非常重要的角色。茂铁基具有化学稳定性、氧化还原活性、富电子性和结构易修饰等特点，使其在功能分子的设计与合成等领域得到广泛的应用。结合茂铁的电化学活性和[Ru（tpy）2]^2＋的光学活性，在[Ru（tpy）2]^2＋分子中三联吡啶的4＇位上引入茂铁基，可以构筑性能优良的光电功能分子。本文介绍了近年来含茂铁基（尤其是具有扩展共轭体系的茂铁炔基或茂铁苯炔基）三联吡啶钌光电功能分子的研究进展，并结合本课题组的研究成果探讨了炔基的引入、炔基位置的不同和炔基长度（由单炔基到双炔基）的变化对该类化合物光电性质的影响。

英文摘要：

Polypyridyl ruthenium （II ） complexes exhibit unique photophysical, photochemical, electrochemical, electron transfer, energy transfer, molecular assembly and molecular recognition properties. Ferrocenyl group has many attractive features, such as excellent reversible redox properties, high solubility in organic media, and high modifiability by organic synthesis methods, and its derivatives remain those distinguish properties in the applications of functional molecules. The ferrocenyl-functionalized terpyridine ligands are particularly interesting, since this type of ligand displays a high binding affinity to many metal ions, offering the thermodynamic driving force for stable metallosupramolecule formation. Furthermore, these ligands can be used for the construction of geometrically well-defined functional complexes which show fascinating properties based on intramolecular electron and energy transfer. This review focuses on the research progress of ferrocenyl-functionalized ruthenium（ II） terpyridine complexes, specially those containing extensively conjugated ferrocenylethynyl and ferrocenylphenylethynyl substituents. Combined with our research results, optoelectronic property alterations of this class of compounds arosed by the introduction, number variation （one or two） and position isomerization of alkynyl are discussed.
