Recent advances in low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS) have provided new opportunities for the investigation of the local geometric, electronic, magnetic, and optical properties of nanostructures. This review focuses ...
This thesis is focused on a combined microscopy technique: energy dispersive spectrometry (EDS) is extended to a three dimensional (3D) microanalysis using a so-called "dual-beam microscope": a scanning electron microscope (SEM) equipped with a focused ion ...
Metal coordination assemblies of the symmetric bi-functional 4,4'-di-(1,4-buta-1,3-diynyl)-benzoic acid are investigated by scanning tunnelling microscopy on metal surfaces. The formation of long-range ordered, short-range disordered and random phases depe ...
During the past decade, various new types of organic nonlinear optical crystals have been developed to overcome the benchmark stilbazolium DAST (4-(4-(N, N-dimethylamino) styryl)-1-methylpyridinium 4-methylbenzenesulfonate) crystal. Here, we review the ace ...
Dynamically switchable supramolecular systems offer exciting possibilities in building smart surfaces, the structure and thus the function of which can be controlled by using external stimuli. Here we demonstrate an elegant approach where the guest binding ...
This thesis details the synthesis and characterization of dinuclear clathrochelates functionalized with groups suitable for supramolecular applications. Their successful incorporation into self-assembled discrete and polymeric structures is related. These ...
In the first part of this thesis we describe the functioning principle of the scanning hall probe microscope (SHPM), and we present a summary of the theoretical and experimental knowledge on the dipolar-coupled Ising ferromagnet LiHoF4. In the second chapt ...
We use the electric field in a scanning tunneling microscope to manipulate the transition between open and close packed 2D supramolecular networks of neutral molecules in nonpolar media. We found that while the magnitude of the applied field is not decisiv ...
In the first part of this thesis we describe the functioning principle of the scanning hall probe microscope (SHPM), and we present a summary of the theoretical and experimental knowledge on the dipolar-coupled Ising ferromagnet LiHoF4. In the second chapt ...
The solvent-induced structural rearrangement of synthetic supramolecular structures typically requires a pronounced change in solvent polarity. We describe a ruthenium-based coordination cage, whose geometry and topology can be altered dramatically by usin ...
