In October 2023, Yuan Li’s Group, Hua-Ping Xu’s group, and Liang Zhang’s group collaborated on the design of self-assembled monolayers (Se-SAMs) on gold surfaces, where selenium replaces thiol as the anchoring group. Through spectroscopic and electrochemical characterization, they demonstrated its comparably dense structure to thiol-based self-assembled monolayers (S-SAMs). Remarkably, these Se-SAMs exhibited air stability for up to 200 days when stored in a laboratory environment.
