Abstract
Aromatski C-nitrozo spojevi s dvije i više nitrozo skupina zanimljiva su građevna jedinica u supramolekulskoj kemiji zbog svojstva povezivanja u azodiokside, a na stvaranje azodioksidne veze moguće je utjecati UV zračenjem i temperaturom. Priređeni su novi aromatski dinitrozo spojevi s različitim premosnicama između aromatskih prstena te je ispitan utjecaj strukture premosnice na samoudruživanje i reaktivnost u otopini, čvrstom stanju i na modificiranoj površini zlata (111). Radi boljeg razumijevanja mehanizma reakcije nastajanja azodioksida u čvrstom stanju provedena su izotermna i neizotermna kinetička mjerenja. Izotermni eksperimentalni podatci obrađeni su nelinearnom regresijom prema empirijskim i mehanističkim modelima, dok su neizotermna mjerenja analizirana često korištenim izokonverzijskim metodama. Nastajanje azodioksida u otopini praćeno je spektroskopijom NMR na više temperatura, dok je udruživanje na uređenim površinama zlata praćeno elipsometrijom. Rezultati upućuju da se na slobodne nitrozo skupine na zlatu veže nekoliko podjedinica aromatskih dinitrozo derivata, dok u otopini nastaju uglavnom dimerne vrste.
Abstract (english)
Aromatic C-nitroso compounds with more than one nitroso groups are interesting supramolecular building blocks due to their property to self-assemble into UV- and thermo-active azodioxy molecular structures. Several new aromatic dinitroso compounds with different spacers between the aromatic rings were prepared. Relation between the spacer structure, self-assembly and reactivity of dinitroso compounds in the solid state, solution and on modified, planar gold (111) surface was examined. Isothermal and non-isothermal solid-state kinetic measurements were performed to analyze reaction mechanisms. Experimental data were analyzed by both semiempirical and reaction-mechanism based model-fitting methods, as well as by common isoconversional procedures. Azodioxide formation in solution was investigated by variable-temperature NMR spectroscopy, while monomer association on the modified gold surface was monitored by ellipsometry. The observed processes indicated that dimer formation was prevalent in the solution, while layers on gold surface consisted of up to several monomeric subunits.
