Synthesis and study of supramolecular properties of azaphthalocyanines usable as sensors
Sikorová, Eliška ; Demuth, Jiří (advisor) ; Kučerová, Marta (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department Department of Pharmaceutical Chemistry and Pharmaceutical Analysis Candidate Eliška Sikorová Supervisor PharmDr. Jiří Demuth, Ph.D. Title of ThesisSynthesis and study of supramolecular properties of azaphthalocyanines usable as sensors Azaphthalocyanines are planar aromatic macrocycles that were derived from natural porphyrins. The basic skeleton consists of four isoindole units which are linked at positions 1 and 3 by azamethine bridges, resulting in an extensive system of conjugated double bonds that give these compounds unique optical and electrical properties. Azaphthalocyanines are widely used as industrial dyes, conductors, photosensitizers in photodynamic therapy, fluorescence quenchers or fluorescence sensors, etc. The compounds synthesized during this thesis can be used as an interesting type of sensors for sensing coordination analytes in solution. That is why this work deals with the study of the supramolecular properties of the synthesized compounds, in particular the ability to form J-dimer type aggregates, which are formed by coordination of the peripheral pyridyl nitrogen to the central zinc cation of the second azapthalocyanine. J-dimers resemble a "step-like" arrangement in contrast to the second type of...

Analýza chovu žirafy Rothschildovy (Giraffa camelopardalis rothschildi) v Zoo Ostrava
Sikorová roz. Valečková, Eliška
In 2014, a breeding group of giraffes was observed in Ostravian zoo. The aim of the observation was to monitor and evaluate individual activities of the animals during the day. The observation took place in both winter and summer season. Elements of behavior had been recorded for four days in each season and compared thereafter. The conclusion of the monitoring is that the most frequent element of behavior was food and water intake, followed by standing, walking and other motion, and often licking of other objects ocurred. Less frequent was excretion and the least frequent sexual behavior. Notes on morphology, bionomy, worldwide distribution, and quantities of giraffes in zoos are summarized and personal evaluation of breeding in Ostrava zoo is mentioned.
