Scanning probe microscopy

Scanning probe microscopy images a sample by scanning a physical probe just above the surface. A variety of different probes and detection modalities can be used to generate either a topological map of the surface or to detect and image some other electromagnetic, physical or molecular characteristic.

    The synthesis of large acenes via traditional solution-chemistry routes is hindered by their poor solubility and high reactivity under ambient conditions. Here, the authors demonstrate the on-surface formation of large acenes, via visible-light-induced photo-dissociation of α-bisdiketone molecular precursors on an Au(111) substrate.

    An understanding of charge dynamics and direct observations of charge generation, transfer and recombination is important to help develop and apply various materials for electronic devices. The authors develop a time-resolved electrostatic force microscopy technique to visually observe charge migration on the nanoscale at a sub-microsecond timeframe.

    Self-sorting is an attractive approach to produce complex supramolecular systems and materials with controlled structures. Here the authors show geometrical complementarity in the self-sorting behaviour of pentagonal and hexagonal pillararenes on heterogeneous surface through layer-by-layer deposition.

    Some porous coordination polymers (PCPs) are known to be flexible and guest-responsive. Now, the guest-induced sharp, reversible structural transformation of the surface of a single-crystalline PCP has been visualized by in situ liquid-phase atomic force microscopy. This local response occurred at a guest concentration that was too low to trigger changes to the bulk crystal.

    Ultrathin metallic films are most often fabricated by atomic or molecular beam epitaxy under ultrahigh vacuum conditions, where it is difficult to control deposition and growth. Here, the authors describe a wet deposition method, using solution-borne gold nanocluster precursors, to regulate growth of atomically flat gold nanoislands on a surface.
