A new heterodinuclear ruthenium platinum complex containing an N-heterocyclic carbene bridging ligand was synthesised and used for photocatalytic hydrogen evolution. The molecular integrity of the unit was proven by mercury poisoning and the lability of terminal halido ligands veryfied with ESI-MS. In situ ligand exchange enhances catalytic performance leading to an almost 500-fold increase in turnover frequency and a significantly improved overall turnover number.

超分子光催化剂在氢气中的合理原位调节

合成了一种新的含有N-杂环卡宾桥联配体的异双核钌铂配合物,并将其用于光催化制氢。汞中毒证明了该单元的分子完整性,并通过ESI-MS证实了末端卤代配体的不稳定性。原位配体交换提高了催化性能,导致周转频率增加了近500倍,并且总周转次数大大提高。
