Publikováno v: Angewandte Chemie (International ed. in English). 59(36)

Photochromic systems with an ultrahigh rate of thermal relaxation are highly desirable for the development of new efficient photochromic oscillators. Based on DFT calculations, we designed a series of 5-phenylazopyrimidines with strong push-pull char

Separation of rotamers of 5-nitrosopyrimidines and estimation of binding constants of their complexes with β-cyclodextrin by capillary electrophoresis

Autor: Sille Štěpánová, Jiří Žurek, Lucie Čechová, Eliška Procházková, Martin Dračínský, Zlatko Janeba, Václav Kašička

Publikováno v: Journal of Chromatography A. 1570:164-171

For the first time, capillary electrophoresis has been successfully employed for the fast and highly efficient separations of a novel type of stereoisomers – planar rotamers (planamers) of four newly synthesized 5-nitrosopyrimidine derivatives. The

Publikováno v: Chemistry - A European Journal. 24:492-498

NMR spectroscopy with in situ irradiation uncovered unique photoswitchable intramolecular hydrogen bonds (IMHBs) in 5-phenylazopyrimidines with two hydrogen bond donors. These compounds form two stable rotamers, each with one IMHB, and the rotamer ra

Autor: Martin Dračínský, Ján Tarábek, Eliška Procházková, Zlatko Janeba, Lucie Čechová

Publikováno v: The Journal of Organic Chemistry. 81:3780-3789

The effect of push-pull interactions in a series of variously substituted 5-nitrosopyrimidines on the strength of intramolecular hydrogen bonds, the height of rotational barriers around formally single bonds, UV-vis spectra and electrochemical behavi
