文摘
The modulation effects of metal nitrites on the hydrogen-bonded supramolecular structure of trimesic acid on a graphite surface have been investigated at the liquid–solid interface by scanning tunneling microscopy (STM). The STM observations demonstrate that the self-assembled hydrogen-bonded molecular networks of trimesic acid (TMA) have been significantly transformed after the introduction of various metal nitrites. It is found that for the nitrite containing full orbital metals (AgNO3 and Zn(NO3)2), the pristine nitrite molecules are directly embedded into the pores within the TMA networks. In contrast, for the nitrite with vacant orbital metals (Cu(NO3)2, Mn(NO3)2 and Fe(NO3)3), the metal–organic coordination networks with various structures are formed due to the incorporations of the metal ions.
