The MMCT excited state of a localized mixed valence cyanido-bridged RuII–Ru III,III2–RuII complex

Abstract

To investigate MMCT excited states of MV complexes, two symmetrical tetranuclear cyanido-bridged localized MV complexes RuIICNRuIII,III2NCRuII have been designed and synthesized. The ultrafast time-resolved transient absorption (TA) spectroscopy experiment reveals that the MMCT rate of 1 and 2 is 0.18 × 1014 s−1 (τ = 5.7 × 10−14 s) and 0.29 × 1013 s−1 (τ = 3.46 × 10−13 s), respectively, which suggests that the MMCT rate or the lifetime of the MMCT excited state may be controlled by a slight change of the substituent group on the metal center.
