Abstract
The complex [CpRuII(dppe)(taae)] {Cp = (5)-C5H5, dppe = 1,2-(PPh2)(2)-C2H4, taae = 10-ethynyl-N,N-di-p-tolylanthracen-9-amine} has been synthesized in a multistep reaction protocol including Sonogashira C,C- and Buchwald-Hartwig C,N- cross coupling reactions. Electrochemical and spectroscopic studies suggest a high degree of delocalization between the ruthenium and triarylamine termini through the anthracene bridge, forming a donor--acceptor (D--A) dye whose -* transitions exhibit charge-transfer character in the monocationic oxidation state.
