Abstract

The invention discloses a linear asymmetric N-Ru-N tris-reduction center terpyridyl ruthenium complex and a preparation method and application thereof, and relates to the technical field of molecular wires, triarylamine substituted terpyridyl is used as a raw material, then the triarylamine substituted terpyridyl is coordinated with triphenylphosphine ruthenium dichloride to obtain the triarylamine substituted terpyridyl ruthenium complex, and finally, the triarylamine substituted terpyridyl ruthenium complex and the trimethylsilylacetylene substituted triarylamine are subjected to the action of potassium fluoride to directly obtain the linear asymmetric N-Ru-N trioxidation reduction center terpyridyl ruthenium complex so as to synthesize the long-distance linear molecular lead model, and the electrochemical method test results show that the two triarylamine end groups connected through the intermediate metal ruthenium have strong electron interaction. Thus, the synthetic design provides a new approach to the construction of molecular wires with longer distances and with remote charge transport performance.
