The influence of 2D nanomaterials on electron transfer across molecular thin films

Here we report the design and formation of electron transfer pathways across self-assembled monolayers (SAMs) after attachment of BN-NH 2 and MoS 2 nanosheets through hydrophobic interaction. The gold electrodes were firstly passivated with methyl group terminated alkanethiols with different carbon chain lengths (n = 4, 6, 8 and 11), followed by the attachment of 2D nanomaterials including boron nitride and MoS 2 nanosheets via hydrophobic interaction. We identified the significant influence of 2D nanomaterials on electron transfer across SAM-modified gold electrodes.
