以三（4-乙基苯基）胺为桥接配体，采用会聚法合成了新型的钌-乙酰基树状大分子。循环伏安图上的多步可逆氧化还原行为和紫外-可见光谱中除第二代树状大分子外钌种类数量的增加导致的深变色表明钌种类之间存在分子内相互作用。
Novel ruthenium−acetylide dendrimers were synthesized by using tris(4-ethynylphenyl)amine as the bridging ligand up to the second generation by a convergent method. Multistep reversible redox behavior in the cyclic voltammogram and a bathochromic shift with an increase in the number of ruthenium species except for the second-generation dendrimer in the UV–vis spectra suggested an intramolecular interaction among ruthenium species.
