Metal-organic hybrid structures are common intermediates in on-surface reactions. To break metal-organic bonds of the hybrid structures needs to overcome a higher activation barrier, which often leads to a series of competitive side reactions and even desorption of target products. Scanning tunneling microscope(STM) has been used to show that the oxygen terminal of 4,4′-dihydroxybiphenyl can effectively reduce the bond breaking barrier of the metal-organic hybridization system, so that the transfer of metal-organic hybrids can be carried out at a lower temperature. This result provides a new method to regulate the intermediates of on-surface reactions.

Key words: Scanning tunneling microscope, On-surface reaction, Metal-organic hybrid structure
