Understanding the Principles of Diastereomeric Complexes of Chiral Urea Derivatives.
Cuřínová, Petra ; Jakubec, Martin ; Storch, Jan ; Holakovský, R.
The main target of this work based on the NMR studies is to elucidate the structural principles which are responsible for the action of the chiral selectors at hand, and thus to be able to predict the new promising structures useful as NMR shift reagents.

Chiral Carbon-rich Materials – From Single Molecule to Functional Layers.
Žádný, Jaroslav ; Storch, Jan ; Strašák, Tomáš ; Krbal, M. ; Hrbáč, J. ; Vacek, J.
Comprehensive study of two different carbon-rich materials properties – [6]helicene and 1-butyl-3-(2-methyl[6]helicenyl)imidazolium bromide – and their thin films is presented. Because of different solubility, diverse preparation approaches had to be employed – electropolymerization and spin-coating. Spectroscopic and electrochemical properties were investigated along with examples of their practical use as detectors of biomolecules (e.g. DNAs). A high application potential of helicene-based carbon-rich materials in development of new optoelectronic devices is demonstrated.

Transition-Metal Complexes with Helical Phosphines.
Beránek, Tomáš ; Žádný, Jaroslav ; Sýkora, Jan ; Storch, Jan
In this work the synthetic pathways were investigated to provide other suitable phosphine derivatives of [6]helicene and their transition metal complexes. Attempts on enantiomeric resolution of prepared helicenes and synthesis of their transition-metal complexes were also done.

Synthesis of Helicene-based Imidazolium Salts.
Jakubec, Martin ; Storch, Jan
In this work, an optimized synthesis of [6]helicenoimidazole was developed. The compound was characterized and its reactivity furnishing conveniently substituted imidazolium salts was explored.

Transition-Metal Complexes with Helical Phosphines.
Beránek, Tomáš
This work follows the synthesis of the palladium (II) complex with 9-phosphanyl[7]helicene, where several structural uncertainties were clarified.\n
