“…In addition, Liu et al. investigated H 2 TBPP thin films on various metal substrates under ambient conditions and found that molecular fluorescence could only be observed from silver and platinum, but not from copper under the present experimental conditions . STM results of the H 2 TBPP film depend on the spectra of the surface plasmons of the substrates.…”

This Minireview focuses exclusively on work with scanning tunneling microscopy to study the self-assembled multilayer films (SAMTs) of organic molecules. The π-conjugated organic molecules form different structures within different monolayers on various substrates. The interplay between molecule-substrate and intermolecular interactions plays a key role in determining the stacking mode of organic multilayer films. Different substrates strongly influence the organic-film growth and electronic properties of the organic molecules. Geometric and electronic structures of SAMTs are important factors that may determine device performance. In addition to the inorganic interface, this Minireview addresses the organic-organic interface. Homo- and hetero-SAMTs of organic molecules are also considered. The subtle interplay between structural and electronic characteristics, on one hand, and functionality and reactivity, on the other hand, are highlighted.

“…Porphyrins are also the object of the investigations of Liu, Nishitani, Iwasaki and coworkers [166,44,174,167,175,176,46]. Contrary to the experiments described above, these measurements are carried out under ambient conditions and the porphyrin films, of average thickness of 4 nm, are prepared by spin-casting.…”

“…A comparison between luminescence spectra obtained for different tip and substrate materials suggests that Ag tips provide a strong increase in the detectable intensity. Spectral regions can be boosted or attenuated by selecting substrate and tip metals and by modification of the tip shape 21, 31, 39–41.…”

The control of light emission on the scale of individual quantum systems, like molecules or quantum dots, is a field of intense current research. One way to induce light emission from these systems is the local charge injection through the tip of a scanning tunnelling microscope (STM). Studies which employ this method have to address one basic question: Does the detected luminescence provide information precisely from the molecule into which charge is injected by the STM tip apex or are the luminescence properties determined by a larger volume?In this article, we focus on the investigation of organic nanocrystals and discuss the relation between the local excitation, the intermolecular coupling and the influence of the STM as a measuring instrument. Choosing pentacene as an organic emitter, we present results, which suggest that the STMinduced luminescence cannot be attributed simply to the emission by a single molecule. We discuss how information about locality can be obtained and comment on the present experimental limitations and possible future improvements.
