Various oxidation states of the catalytically active cobalt center in a covalent dyad were electrochemically prepared and the light-induced excited-state processes were studied. Virtually identical deactivation processes are observed, irrespective of the oxidation state of the cobalt center, varying from Co to Co, indicating the absence of oxidative quenching within the dye-catalyst assembly.
电化学制备了共价偶联物中催化活性钴中心的各种氧化态，并研究了光诱导激发态过程。无论钴中心的氧化态如何，从 Co 到 Co，观察到几乎相同的失活过程，表明在染料-催化剂组装体中不存在氧化猝灭。
