Kurzfassung:
Pillarplexes represent a family of coinage-metal-based supramolecular organometallic complexes (SOCs). In this thesis, the pillarplexes were tested for their stability and biological activity with regard to their potential in medicinal applications. In addition, three novel SOC-ligand systems were developed. Another focus of this thesis is the cyclic trinuclear complexes (CTCs). The structural and photophysical properties of the gold(I) CTC Au3(1-methylimidazolate)3 were investigated.
