Abstract
Through-space electrical conduction in paddlewheel-type homovalent dinuclear complexes remains poorly understood, despite the numerous reports on these complexes. Herein, the electrical conduction of new Ru2(II,II) complexes with 2-pyrenecarboxylate (pyrCOO-) ligands, [Ru2(pyrCOO)4X2]∙n(X) (where X = DMF (Ru-DMF), NMP (Ru-NMP), DMA (Ru-DMA)), was investigated. The dimensionality of π-stacking interactions between discrete molecules in Ru-DMA is higher (two-dimensional) than in Ru-DMF and Ru-NMP (stair-like one-dimensional). Nevertheless, Ru-DMF, which contains a slight amount of organic radicals, exhibited the highest electrical conductivity. This suggests that the large overlap and high dimensionality of π-stacking interactions among the complexes, along with a slight organic radical impurity, contribute to the increased electrical conductivity.
期刊介绍：
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
