The hexachlorocerate(III) anion, [CeCl], was found to be a potent photoreductant in acetonitrile solution with an estimated excited-state reduction potential of -3.45 V versus CpFe. Despite a short lifetime of 22.1(1) ns, the anion exhibited a photoluminescence quantum yield of 0.61(4) and fast quenching kinetics toward organohalogens allowing for its application in the photocatalytic reduction of aryl chloride substrates.
六氯高铈(III)阴离子，[CeCl]，被发现是一种在乙腈溶液中具有强大光还原能力的物质，其激发态还原电势估计为-3.45 V 相对于 CpFe。尽管其寿命很短，只有 22.1(1) ns，但该阴离子表现出 0.61(4)的光致发光量子产率和对有机卤化物的快速猝灭动力学，使其能够应用于芳基氯底物的光催化还原。
