- Synthesis and properties of chromophore-functionalized monovinylsilsesquioxane derivatives
-
A facile and efficient Pd-based Suzuki-Miyaura coupling reaction leading to mixed chromophores with styryl fragments, enabling their further application, is presented. We also disclose their use in the formation of monofunctionalized silsesquioxanes with a chromophore group covalently bound to a T8 core that have been prepared via a cross-metathesis reaction. These new materials were studied in terms of their photophysical and also thermal properties.

- Copper-catalyzed arylation of polycyclic aromatic hydrocarbons by the PO group
-
The first example of a directed and regioselective arylation of polycyclic aromatic hydrocarbons (PAHs) by using a PO directing group is reported herein. The protocol uses a cheap copper catalyst, and results in a breakthrough meta-selective C-H functionalization of arylphosphine oxide compounds. Substrates with potential fluorescence properties, for example, pyrene and fluoranthene, were successfully arylated under the system, thus achieving an efficient modification of fluorescent molecules containing the PO functional group.

- Synthesis of Positional Isomeric Phenylphenalenones
-
A series of isomeric phenylphenalenones in which the phenyl ring is located at all possible peripheral positions of the phenalenone nuclei was synthesized. The structural characteristics of the series, in which topological variation is permitted with minimal electronic disturbance, could, in principle, allow for easy pharmacophore recognition when the compounds are aligned in steroidomimetic conformations.

- Synthesis of precursors for large-diameter hemispherical buckybowls and precursors for short carbon nanotubes
-
We report herein the synthesis of six precursor molecules for the rational synthesis of isomerically pure armchair, zigzag, or chiral single-walled carbon nanotubes (SWCNTs). The polycyclic aromatic hydrocarbons possess the required carbon connectivity for the generation of extended hemispherical buckybowls with predefined geometry through intramolecular cyclodehydrogenation. The precursors for the short carbon nanotubes and the large-diameter hemispherical buckybowls have potential for the rational initiation of single-chirality SWCNT growth on metal surfaces. The options for the construction of precursors for various SWCNT chiralities based on the suggested synthesis strategy are presented.
