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。
Polypyridine ruthenium complexes play a very important role in photochemistry, photophysics, electrochemistry, electron transfer, energy transfer, molecular assembly and molecular recognition. Ferrocene has the characteristics of chemical stability, redox activity, electron-rich and structural modification, which make it widely used in the design and synthesis of functional molecules. Combining the electrochemical activity of ferrocene and the optical activity of [Ru (tpy) 2] 2+, the introduction of ferrocenyl groups into the 4 ’position of the terpyridine in the [Ru (tpy) 2] 2+ molecule allows for the formation of Photoelectric functional molecules. In this paper, the research progress of the photoelectric functional molecules containing ferrocenyl groups (especially the ferrocenyne or the ferrocenylphenynyl) terpyridyl with the extended conjugated system has been introduced in this paper. In combination with the research results of our group, The introduction of groups, the different positions of alkynyl groups and the alkynyl length (from monynyl to diynyl) changes the photoelectric properties of these compounds.
