摘要

杂金属低聚物单层在界面电催化方面优于单体，但其合成复杂性仍不可预测。在这里，我们提出了一种通过工程单体组成和异齐聚物单层序列来系统优化界面电催化剂的总体策略。这些单分子膜是通过电化学测序将Ru(II)- qpyl1l2 （qpy =季吡啶，L1 = 9-（4-（吡啶-4-基）苯基）- 9h -咔唑，L2 = 4-乙烯基吡啶）和Ru(II)- bdal1l2 （bda = 2,2'-联吡啶-6,6'-二羧酸盐）添加到自组装的单分子膜上制备的。定量工程电导、催化电流密度和过电位作为分子长度、组成和序列的函数进行了研究。作为分子长度的函数，均聚物单层的催化电流密度提高了至少20%。交变杂七聚体单层膜的催化电流密度分别是自组装单层膜和同七聚体单层膜的10和2.4倍。我们的工作为优化和提高已知界面分子材料的催化性能开辟了一条简单有效的途径。

Enhancing the performance of interfacial electrocatalysts by engineering the monomer composition and sequence of metallo-oligomer monolayers†

Hetero-metallo-oligomer monolayers should be superior to their monomers for interfacial electrocatalysis. Here, we present a strategy to optimize and enhance the performance of interfacial electrocatalysts by engineering the composition and sequence of distinct metal complexes. The catalytic current density of the alternating hetero-heptamer monolayers is 10 and 2.4 times higher than those of the self-assembled and homo-heptamer monolayers, respectively.
