A bis(TTF-butadiynyl) ruthenium D–D′–D complex, with intramolecular electronic interplay between the three electron-donating electrophores, was easily converted through a cycloaddition–retroelectrocyclization with TCNQ into a D–A–D′–A–D pentad complex, which exhibits an intense intramolecular charge transfer together with an electronic interplay between the two acceptors along the conjugated organometallic bridge.

TTF和扩展的TCNQ电泳之间沿钌双（乙酰胺）连接器的电子相互作用。

双（TTF-丁二炔基）钌D-D'-D络合物，在三个给电子电泳体之间具有分子内电子相互作用，可以很容易地通过TCNQ的加成-逆电环化反应转变为D-A-D'-A-D五单元复合物，它沿着共轭有机金属桥表现出强烈的分子内电荷转移以及两个受体之间的电子相互作用。
