Current Induced Tunneling Spectroscopy (CITS) maps coordination bonds in supramolecular metal assemblies with submolecular resolution. This technique aids in the controlled, bottom-up construction of functional 2D molecular designs.

Area of Science:

  • Surface Science
  • Supramolecular Chemistry
  • Nanotechnology

Background:

  • Scanning Tunneling Microscopy (STM) provides structural and electronic information but struggles with spectroscopic interpretation of molecular assemblies.
  • Distinguishing structural and electronic data in STM images of supramolecular metal ion assemblies is challenging.

Purpose of the Study:

  • To present a room temperature scanning tunneling spectroscopy (STS) protocol, Current Induced Tunneling Spectroscopy (CITS), for analyzing supramolecular metal ion assemblies.
  • To demonstrate CITS's capability in achieving submolecular resolution for imaging local tunneling probabilities.

Main Methods:

  • Deposition of supramolecular metal ion assemblies onto highly orientated pyrolytic graphite (HOPG) substrates.
  • Application of Current Induced Tunneling Spectroscopy (CITS) for imaging.

  • Validation of assembly size using X-ray crystallographic data.
  • Consistency checks via Density Functional Theory (DFT) calculations.

    • Main Results:

    • CITS successfully rendered local tunneling probabilities with submolecular resolution for 1D and 2D supramolecular metal ion assemblies.
    • The technique allowed exclusive mapping of coordination bonds in transition metal assemblies due to the unique electronic structure of metal centers.
    • Submolecular spatial resolution was achieved in mapping coordination bonds.

    Conclusions:

    • CITS is a powerful tool for analyzing supramolecular metal ion assemblies at the submolecular level.
    • The technique enables precise mapping of coordination bonds, crucial for understanding assembly structure.
    • CITS holds significant potential for directed bottom-up construction and manipulation of functional 2D molecular systems.
