Complexation Properties of Aza[n]phenacene Ligands.
Váňa, Lubomír ; Žádný, Jaroslav ; Storch, Jan ; Církva, Vladimír
This work is aimed at the synthesis of new aza[n]phenacenes 2 (n = 4 or 5, Ar = phenyl or 2-pyridyl), where [njphenacenes 1 with ö-lactam ring are used as starting material. The resulting compounds are subsequenttly investigated in terms of their complexation properties with transition metals (Cu, Ni, Co, Pt, Ir) due to their potential application as photoluminescent complexes.

Transition Metal Complexes with Aza[n]phenacene Ligands.
Váňa, Lubomír
This work is aimed at the synthesis of new aza[n]phenacenes 2(n = 4 or 5, Ar = phenyl or 2-pyridyl), where [n]phenacenes 1 with δ-lactam ring are used as starting material (Scheme 1). The resulting compounds are subsequently investigated in terms of their complexation properties with transition metals (Cu, Ni, Co, Pt, Ir) (e. g.Figure 1) due to their potential application as photoluminescent complexes.

Synthesis and Functionalization of Phenacenes Containing δ-Lactam Ring.
Váňa, Lubomír ; Církva, Vladimír ; Pfleger, Jiří ; Storch, Jan
This work is aimed at the development of a new efficient methodology towards the synthesis of various aza[5]phenacenes containing δ-lactam ring in their structure. Possibilities of their functionalization or derivatization are also discussed, along with complexation properties of suitable aza-derivatives as ligands in transition-metal complexes. The resulting compounds are investigated in terms of their material properties, especially for the formation of thin film structures capable of an efficient semi-conductivity or their potential application as photoluminescent complexes in OLEDs.
Synthesis of Steroid Derivatives for In Vitro Diagnostics.
Kos, Martin ; Váňa, Lubomír ; Žádný, Jaroslav ; Storch, Jan
This work is focused on the synthesis of novel steroidal androgen derivatives consisting of a steroidal skeleton, a spacer and imidazole ring or a primary amine functional group. The starting material for the synthesis is represented by commercial available hydroxy-androgens, which are further modified. First, the hydroxyl group is attached to the spacer and then connected to the desired imidazole or the protected primary amine. The above described derivatives will be utilized for development of analytical kits for a determination of the free steroid hormone.

Synthesis of Amidoazaphenacenes for Applications in Organic Molecular Electronics.
Váňa, Lubomír ; Storch, Jan ; Církva, Vladimír
This work is focused on preparation of amidoazaphenacenes by photocyclization of various ortho-chloro-substituted aromatic amides. Their amide functional groups can make hydrogen bonds, which have a positive effect on formation of a stable supramolecular structure to facilitate the charge carrier transport in thin solid film.\n
