A robust surface between molecules and electrodes is important for the construction of molecular and electronic devices. In their Research Article on page 20499, Y. Tian et al. demonstrate that the Au−C≡C bond is highly stable under thiol‐abundant conditions and shows better electrochemical performance than Au−S and Au−Se bonds. Based on the remarkable performance of the Au−C≡C bond, an Fe 2+ electrochemical sensor was developed and applied in the biosensing and analysis of Fe 2+ in live mouse brain.
